Last night’s Saint Laurent fashion show in LA was a star-packed event, with big-time Hollywood stars, musicians and fashionistas all hitting the red carpet and posing up a storm for the paparazzi. Check out the dazzling A-listers like Courtney! Gaga! Emma! Justin! and more after the jump.

The goddess Courtney Love (who epitomizes the YSL look, of course)

Demi Moore looking like she’s been sucking the life-force out of Jordana Brewster. How DOES she stay so young?

Tousled moppet Lady Gaga

Justin, who – I’M JUST GOING TO SAY IT – seems to be channeling a young Errol Flynn with his mustache, goatee and those adorable downward sloping eyebrows.

Future Academy Award winner Sylvester Stallone with his daughters Sophia and Sistine (He… named his daughter SISTINE? How did I never know this?)

Sisters Elle and Dakota Fanning (Elle is looking VERY rock n roll)

Pamela Anderson with sons Brandon Lee and (YSL model) Dylan Lee

Let’s have a closer look at Dylan, shall we?

Melania Trump? No, it’s supermodel Rosie Huntington-Whiteley. But if she ever gets the chance to play First Lady Melenia, she ought to jump at it.

Jane Fonda, looking every inch the modern grande dame.

Dominic Sherwood, whom you might remember as Taylor Swift’s love interest in the “Style” video, and who appears to have one blue eye and one blue-and-red eye. ZEXY!

Emma Roberts

Good guys Ellen DeGeneres and Portia De Rossi

90210‘s Shenae Grimes and date, who seem to have gotten mixed up and thought they were attending last week’s Grease Live! event.

… and the best dressed of the night? Rock widow Linda Ramone and guest in 17th century Flemish hats. Both excitingly retro and completely au currant, darling
