Fitness buff Madonna is taking her love of working out to the next level. The Material Girl has announced that she's opening her own line of gyms, dubbed "Hard Candy."

The first gym, a 30,000 square foot state of the art center, is to open in Mexico City next month, and an additional ten are already in the planning stages in Russia, Europe, Asia, Brazil and Argentina.

None for the US at the moment, but I'm sure Madonna will strong-arm her way into the market fairly soon!

Britney Spears headed to the office with her agent beau Jason Trawick this morning just hours after a new track from her upcoming album, with explicit sexual lyrics, was leaked.

In a new song, titled "Pleasure You", Britney sings about doing anything to please her man.

One lyric reads:

"If you want to get rough in that lay on your back, I got the max suddenly I'll pull you through whatever just to pleasure you."

The execs at Jive were apparently none too happy about the leak, according to Radar, and it doesn't seem like Britney was either! The pop princess seemed serious as she headed into her agency, perhaps to discuss where the breach came from.

In other news, do you think she's singing about getting "rough" with Jason? And he doesn't exactly strike us as the most sexually open guy -- how do you think he would feel about having his sex life on display?

Christina Aguilera is proving to her fans that her split with soon-to-be ex hubby Jordan Bratman will not have an impact on her famous pipes. XTina wowed the Las Vegas crowd who packed the Planet Hollywood Theater for the Justin Timberlake and Friends Concert for Shriners Hospitals for Children.

Before Ms. Aguilera, 29, hit the stage, Justin Timberlake gave his longtime friend the following introduction:

"This next act is very dear to me. I've known this woman, this lady, since I was 10 years old. Multi-platinum, five-time Grammy award-winning, over 46 million albums worldwide and no contest ... the greatest voice of my generation."

Loves it! Although Christina stole the show, other performers included Elton John, Lady Antebellum, Selena Gomez, Salt-N-Pepa and Diddy.

Can you blame him though? Just look at all the other singing and dancing talent he was competing with!

Oscar-nominated actor Ryan Gosling opens up about his past life on The Mickey Mouse Club to Interview Magazine, where he starred alongside Britney Spears, Christina Aguilera and Justin Timberlake…

”It was kind of depressing because when I got there, they realized that I wasn’t really up to snuff in comparison with what some of the other kids were able to do. I remember one time they put four of us in a dance routine, but I was so off. I was on the end, so they just pushed the shot in closer on the other three guys to frame me out. I would just come in at the beginning of the show and then come back at the end, and occasionally I’d have a sketch here or there, but I didn’t end up working that much, which was disheartening.”

Gosling – who’s interviewed by his Crazy, Stupid, Love co-star Steve Carell – danced backup for the trio for two years.

So random!

Next up for the singer and dancer turned actor? Blue Valentine, co-starring Michelle Williams, which opens in select theaters on December 31st.

He’s already been sentenced to 11 months in prison for violating his probation, but T.I. won’t be charged for the incident that put him there.

The D.A. has decided not to go ahead with the case because T.I. is already having to serve the time no matter what -- the arrest itself was the violation.

T.I. spent a year in prison on a federal weapons charge just last year, and was not even half way through a three-year probation term when he was slapped with this latest sentence.

No word if the charges against T.I.'s wife Tameka, who was a passenger in the car at the time of the arrest, will also be dropped.

Last night Tila Tequila turned 29, and she celebrated her birthday at Mr. Chow in Beverly Hills. The reality TV turned porn star rolled up in her blue Lamborghini nearly three hours late, but maybe because she was scared of being attacked? Someone obviously wasn't a big fan of Tila, as we spotted nearly a dozen posters with hateful handwritten messages written across them outside the restaurant. Hmm, who would have done this?!

Janet Jackson stopped by ABC's Good Morning America to talk about her upcoming role in the drama, For Colored Girls … and to squash engagement rumors.

Miss Jackson, who’s been dating business man Wissam Al Mana since early this year, breaks down her relationship status to GMA’s Robin Roberts. She says:

“He’s a very private man, so I don’t talk about our relationship. I’m not engaged, I will say that.”

She adds that her role in Tyler Perry’s flick is “so bold and so shrewd.” Can’t wait to see Miss J in a whole new light!

He's got a thing for blonde babes, and she's reportedly dabbled with the older man market, so why not!?

Taylor Swift was backstage at Saturday Night Live the other night to support her BFF Emma Stone, and sources tell Lainey Gossip that Jake Gyllenhaal was back there with her! She was "totally into him," and after witnessing the giggling and discreet hand holding, the spy noted that the relationship between the two “was more than just friends."

After SNL, the new duo left together, and they've been spotting getting brunch and shopping in NYC. Really?! Jake's rep had no comment when asked if the two were an item, and we're curious to see what happens with this relationship ... and totally jealous of Taylor if it's true!
