John Mayer Steals Katy Perry’s Self-Promotional Semi Truck Idea

Katy Perry made a memorable statement in late July when an golden semi truck emblazoned with the title and release date – Prism, October 22 – of her upcoming album took a spin through the streets of Los Angeles.

Now her beau John Mayer is following in her tracks, quite literally.

Though his album, Paradise Valley, is already out, Mayer is promoting the South American leg of his tour with a similar semi – plastered with the album’s art, a photo of Mayer standing alone in a dreary, desolate valley, mountains rising up in the distance.

“Off this week and then next up is South America!! Are you ready for JM??” he wrote, posting a photo of the truck on Facebook. Then he threw in the hashtag #MAYERISBACK.

Will Mayer also “ride” around in the big-rig, a la Perry? Will his truck get bumped up in a Walmart parking lot, too? Will he then pop out when he arrives in Buenos Aires, Argentina, for his next show?

So many questions, so few answers.

John Mayer: A Dating History

Before he became Katy Perry‘s main squeeze, John Mayer had quite the dating history.

The Grammy Award winning crooner and notorious lothario has wooed many of Hollywood’s hottest women. Let’s take a look back at some of his former lady loves, shall we?

We don’t really know the secret to this Mayer’s game, but he has sure landed a few famous catches. Maybe it’s his scruffy good looks, his soothing melodies, or his goofy boyish charm. Perhaps it’s lyrics like “your body is a wonderland,” “you’ve got a face to call home” or “I loved you, grey sweatpants, no makeup, so perfect.”

This is a guy who attracted big name beauties like Jennifer Aniston and Jessica Simpson, so he must have done something right.

The 35-year-old singer’s latest girlfriend is pop superstar Katy Perry. The pair even collaborated on a sweet track called “Who You Love” for his upcoming album, Paradise Valley.

But who did John love in his past? Launch the gallery, above, for a John Mayer romance rewind.

This Week In Hookups, Breakups And Makeups

With Valentine’s Day celebrations in full force this week, love was all around for Hollywood’s hottest couples.

Katy Perry and John Mayer hit a high note at the Grammy Awards on Sunday, where they cozied up in their front row seats during the award show. Out of the spotlight, the pair have favored spending quality time together – a bond that has given Mayer a new perspective when it comes to romance.

“For the first time in my life, I don’t feel like I’m in a celebrity relationship,” he said during an interview with CBS Sunday Morning.

Meanwhile, across the pond, another photo scandal rocked Prince William and Kate Middleton when a tabloid magazine released invasive shots of the expectant royal in a bikini while vacationing in Mustique, a small private island in St. Vincent and the Grenadines.

In happier news, legendary comedian Steve Martin revealed he became a first-time father at the age of 67. In December, he and his wife Anne Stringfield welcomed a baby, according to the New York Post.

Katy Perry & John Mayer

From swanky soirees to coffee runs, it seems as if the singers might have finally found a compatible rhythm in their budding romance. The pair have been inseparable since going public with their relationship in 2012. And after keeping close at the Grammys, Perry and Mayer’s love looks stronger than ever.

How has their relationship helped Katy after her divorce from Russell Brand?

Whitman’s opinion: It appears that her new relationship has helped her move past the marriage and divorce. It seems that her relationship with John has given her more confidence and she seems to be very happy. I think it is giving her hope for a better future, whereas going through a divorce it is difficult to imagine a bright future. This relationship seems to make her happy.

Is John the real deal, or just a playboy?

Some men appear to be playboys until they find the right partner. Many men don’t want to settle down or stay with one woman, because they know that there is not a future with the person they are with. So they move from one woman to another. This is how we get clear on the type of person we want to be with. That is what dating is all about. At least for now, John seems to be very happy with Katy and is the real deal.

Considering his dating record, what steps does John need to take to prove he’s a dedicated boyfriend?

I believe he needs to continue to focus on his relationship with Katy. He needs to continue to stay grounded to himself and she to herself. Relationships are never easy no matter who you are, but even though there was relationship trouble for both of them in the past it does not mean that they can’t find true love, connection and happiness. John has nothing to prove, he just needs to stay true to himself and the relationship.

Steve Martin & Anne Stringfield

The funnyman joins an A-list group of Hollywood dads who’ve had kids well past their prime. In December, the famed funnyman and his wife welcomed a baby. The couple “has been very private” since the arrival of their bundle of joy.

What are the pros and cons of becoming a first-time dad later in life?

Whitman’s opinion: The pros are that later in life you are more settled in your finances and your career. There is a more secure environment and less stress due to the feeling of security. You also know the type of partner you want to be with. Typically later in life marriages last longer because of this clarity. There is more patience for certain things such as going at the pace of the child. Later in life you tend to appreciate the small moments that most people miss when they are younger. There is more awareness of being in the present moment.

Cons: You don’t have as much energy later in life as you did as a younger dad. There is always a generation gap between parents and children, but the gap is wider when there is more years between the parent and child. If both the parent and the child can be open and allowing of each other that helps in this generation gap. If the communication is not strong and healthy the age difference can put a wedge between the parent/child relationship.

Prince William & Kate Middleton

In yet another royal family controversy, the Duke and Duchess of Cambridge are keeping a united front after Star Magazine released photos of the pair enjoying a romantic holiday together in a private island in St. Vincent and the Grenadines. Controversies swirled as the publication’s cover featured Middleton in a blue bikini with the headline: “Kate Shows Off Baby Bump.”

Will the spotlight wear on Kate and affect the couple’s marriage?

Whitman’s opinion: I think with any celebrity in the public eye that has the paparazzi taking pictures or chasing them, it does affect them. As poised and centered as Kate is, she is still human and it is most likely affecting her. This can affect the couple’s marriage, but it does not have to in a negative way. Any situation that they face in their very public marriage can actually bring them closer together. They both understand what the other is going through and this can help them deeply relate to one another. They need to be careful not to take this out on one another, but to talk about their anger, frustrations and support one another.

What can they do to keep their privacy once their first child arrives?

Whitman’s opinion: Other than staying home and never bringing the child out in public, give opportunities to have the media take pictures under a controlled environment that they agree to. Because of the nature of who they are, they will always need to be aware of the fact that they do not have privacy anymore, especially when they are outside. They have to prepare themselves to be photographed and make peace with that, or it will continue to anger them. They really have to accept the fact that they are super celebrities and that the paparazzi will do whatever they can to get their photos. They can’t fight it, but can accept it and take steps to protect themselves.
