Hollywood gave a wave to the new royal couple Saturday night as Prince William and Kate Middleton, the Duchess of Cambridge, turned out for BAFTA's Brits to Watch 2011 gala.

Not only did some of LA's biggest celebrities get a bit star-struck seeing the young couple, fans outside the Belasco Theater were shrieking with excitement as they caught a glimpse of Kate, 29, in her white Alexander McQueen dress and William, clad in a traditional black tuxedo.

Nicole Kidman, Jennifer Lopez (who brought her mom along), Barbra Streisand and others shined on the red carpet before everyone entered for for a formal dinner.

Vice chairman of the British Academy of Film and Television Arts, Duncan Kenworthy, addressed all of the guests before the event began, educating those who had never met the royals, how to address Will and Kate:

"They want to meet all of you. They will try and chat to all of you this evening. When you meet them, you don't have to bow and curtsy. You can call them whatever you feel: 'Your Royal Highness,' 'Sir,' 'Ma'am,' 'William' and 'Kate' – just as the mood takes you."

Everyone minded their P's & Q's, with most of the night's biggest names arriving well ahead of the 8am start time -- a rarity in a town where everyone's always late.

Barbra Streisand chatted with Entertainment Tonight on Friday when she was honored at the Grammy’s Musicares event in Los Angeles, and she talked about everything from Glee to politics.

Though Streisand says Lea Michele is "pretty good" and she doesn't seem to have a problem with the show's cover of her tune "Funny Girl", she reveals that she won't be making a special appearance anytime soon. “Not if I can help it,” Barbra replied when asked if she'd make a cameo. “I have seen some of the episodes. My niece, my young niece, saw ‘Funny Girl’ on DVD and said, ‘How come you’re singing so many songs from ‘Glee’?’”

Streisand didn't comment on whether she would be active in President Obama’s re-election campaign, but when asked how she felt about Sarah Palin’s possible bid for office, she quipped, “I wouldn’t be encouraged if I heard Sarah Palin’s going to run.” Burn! At least Lea Michele got some praise from the 68-year-old singer.

Barbra Streisand will hit the stage at this year's Grammy Awards, according to Entertainment Tonight.

The 68-year-old performer, who has won numerous Oscar, Grammy and Emmy Awards, will be joining other singers for the award show including Mick Jagger, the Rolling Stones, Gwyneth Paltrow and Cee Lo Green.

Streisand will be awarded the Person of the Year award on February 11th from MusiCares, a foundation that aids aspiring musicians who have medical, financial or personal needs.

Her performance at the 53rd Annual Grammy Awards will take place this Sunday, February 13.

Barbra Streisand is speaking out on the recent photos of Jennifer Aniston in Harper's Bazaar ... in which the actress channels the legendary singer.

"I was very flattered that Jennifer Aniston chose to interpret my style with the photos in Harper's Bazaar. She's a delightful person, and I think she did a wonderful job. If only she had a bump on her nose."

I guess it's true ... imitation is the best form of flattery.

Loves it!

Last night U2 performed at the Rose Bowl in Pasadena, and there was no shortage of stars who attended the concert.

We caught everyone from Barbra Streisand (who looked MUCH younger than her 67 years) to a hunky, bearded David Beckham. But back to Babs - can you believe what she's wearing? She's dressed sexier than her teenage granddaughter Eden! Kudos to her though ... she looks amazing!

Colin Farrell brought his girlfriend, Demi showed up sans Ashton, Paris and Doug made an appearance, and we even spotted Michael Bay with a girl who looks like some sort of a Penthouse pet. Ahh, just another night in Hollywood!

Barbra's up to her old tricks again!

Hanging around her Malibu home, eating and ordering people around. All in a day's work!

Aaahhnold driving a war vehicle, Matt Dillon picking his nose (during lunch, no less!), and Babs exposing her derriere?! What's this world coming to!

Are you surprised? We spotted the quintessential diva, Barbra Streisand, directing some workers at her Malibu mansion while carrying around a shrimp plate.

Think she offered anyone some shrimp?
