Christina Aguilera works it while she films scenes for her upcoming movie Burlesque on Hollywood Boulevard in Los Angeles.  Christina co-stars with, among other stars, Cher who has had high praise for Christina:

“I’m shocked but she’s really good. The other day we were hamming it up so badly, so old, like vaudevillian. She was keeping up! She was hot. Her game is good

In between takes Christina looks like she could use some sleep.  Maybe she had a wild Valentine’s Day weekend?

Lady GaGa has made a grand entrance that only she could pull off.  I don’t even know what to say.  Nice drapes? I would be seriously pissed if she sat in front of me with that contraption on her head.

Lady GaGa left organizers of the Brit Awards (going on now) scrambling at the last minute as she ditched plans to do an elaborate musical number to instead pay tribute to Alexander McQueen who took his life last week after becoming inconsolable over his mother’s death the week prior.

Lady GaGa has been left devastated by her friend’s death. Says a source:

‘She was a huge fan of his talents as a designer – but more importantly a good friend of his. And she is determined her show will be a tribute.

‘At the Brits, it was going to be a typically wild Lady Gaga show – but now she has decided she will deliver a much more sombre performance.’

She was to have performed Poker Face but will instead perform Telephone (3 new promotional stills attached, two of which she has telephone headgear wrapped around her noggin) and Dance in the Dark.  Judging by her arrival outfit it will be ‘sombre a la GaGa‘.

Gerard Butler and Madonna look very relaxed and happy as they attend an event sponsored by Braham in Rio de Janeiro along with Rodrigo Santoro.

This is Rio’s Carnival time of year and who better to party with skantily-clad women than Gerard Butler?

“You know I’ve done other fittings where you have to wear underwear and you’re kind of uncomfortable because they look funny or it doesn’t fit well. They made it really easy. The clothes fit great – there wasn’t anything that was riding up, so you don’t feel uncomfortable posing.”

“But now my nude a*s is going to be all over the billboards, we’ll see what my mother thinks!”
