Guy Laliberte [Photo: Steve Granitz/WireImage]Guy Laliberte is the wealthiest fire-breather in the world, and he's getting even richer. The former street performer founded Cirque du Soleil in 1984 and still owns 80% of the company; revenues topped $1 billion for the first time this year, placing his personal net worth at $2.6 billion, up $100 million last year.

The increase in Laliberte's fortune can be partially traced to music—more specifically, the success of Michael Jackson: The Immortal World Tour, a joint venture with the Jackson estate. Since its October debut, the show has grossed over $2 million per night across 85 show dates, with hundreds more to come.

But Perry's words aren't just a simple denial: Turns out the song had been written (and leaked) in 2010, just two months into the superstar couple's quickie marriage.

Creepy omen, or simple coincidence?

In a recent interview with Parade, the 36-year-old Latin singer explained why he called Kournikova his "wife" at a concert in Russia last year, yet hasn't popped the big question. He told the magazine, "It was just meant to be sweet in the moment. I honestly didn't mean to confuse people. I thought it'd be easier for the audience to understand than if I said "my girl."

The story broke over on the U.K.'s Daily Mail. The paper reported that the 18-year-old Bieber bought the Hollywood Hills mansion as a kind of birthday gift to himself. Tough life this kid's got.

Avril Lavigne has gone from skater girl to seductress in her newest video "Goodbye." Dedicated to her fans as she closed out the last leg of her recent "Black Star" tour, the video follows her around celebrity hideout Chateau Marmont in Los Angeles wearing little more than heels and black lingerie. As sexy as she looks, the 27-year-old Canadian singer is practically unrecognizable out of her tomboy uniform of a t-shirt and jeans. Has she gone too extreme in an attempt to be more mature?

Jon and Dorothea Bon Jovi in 2010 [Photo: Gregg DeGuire/FilmMagic]As Jon Bon Jovi celebrates his 50^th birthday on March 2, there's also another milestone worth noting: He's also one of the very few major rock stars to make it to the half-century mark while still on his first wife.

The namesake frontman of Bon Jovi has been married to his high school sweetheart, Dorothea, since they wed in a seemingly quickie ceremony at Las Vegas' Graceland Wedding Chapel in 1989. Jon and Dorothea had been on and off as a couple for a decade prior to that. But, aside from a brief pre-marital dalliance with actress Diane Lane, the rocker hasn't been publicly linked to any other sweeties besides his first crush.

Go ahead and say it, fans: He gives love… a good name.

It is with a very heavy heart that I find myself today, for the first time ever, in the regrettable position of having to write about the death of a celebrity crush. My very first celebrity crush, in fact: Davy Jones, aka the Cute Monkee, who tragically died of a heart attack this week at only age 66. Today I am feeling a personal loss, but more importantly, Davy's passing is a huge loss for music in general, even if he and his bandmates didn't initially get the critical respect they deserved.

It's all those other stars who died from monkeying around, succumbing to the temptations associated with fame. Not Davy Jones, who seemed to be the picture of good habits and health — if not the portrait of Dorian Gray — before he died of a heart attack at 66 Wednesday morning in Florida.

"You know I used to be a heartthrob and now I'm a coronary," Jones said in an interview last August with the Broadway World website, surely little realizing that his quip might actually serve as a witty, spooky epitaph.
