Johnny Depp Parties With Amber Heard and 16-Year-Old Daughter, Lily-Rose, at Star-Studded Stella McCartney Bas

Hollywood was out in full effect on Tuesday night at Amoeba Music in Los Angeles, where designer Stella McCartney presented her Autumn 2016 collection in front of her A-list pals. Celeb attendees at the huge bash included Johnny Depp, Gwyneth Paltrow, Katy Perry, Kate Hudson, Leonardo DiCaprio, Pink, Mary J. Blige, Sarah Silverman, Chelsea Handler, Nicole Richie, Kate Upton, and Orlando Bloom.

Depp made the party a family affair, bringing along his 16-year-old model daughter Lily Rose Depp, and his wife, 29-year-old Amber Heard. A source tells ET that 52-year-old Depp was being "very sweet" with Heard during their night out, keeping his arm around her. Lily-Rose was also not alone, as she was spotted walking around the party with a male friend.

Depp later took to the stage for a surprise performance with Marilyn Manson to pay a tribute to the late David Bowie, who died on Sunday after an 18-month battle with cancer.

As for all of the A-list run-ins, surprisingly, our source says Perry and Bloom didn't interact with one another, although they were spotted looking very friendly at The Weinstein Company and Netflix Golden Globes after-party on Sunday night. Instead, Perry danced with Hudson, and also hung out with Girls star Jemima Kirke.

It was apparently a boys night out for Bloom, who our source says was happily dancing with DiCaprio to the Beach Boys' classic "Surfin' USA."  The Beach Boys' Brian Wilson was a surprise performer at the event, and in an Instagram video taken by model Jamie Wise, DiCaprio -- wearing a newsboy cap -- is seen chatting with Bloom during the performance.

Of course, this being a fashion party, the celebs weren't slacking when it came to bringing the style. Check out Paltrow, Richie, and Blige's fierce looks.

Paltrow had an especially close encounter with the woman of the hour, when the actress pinched McCartney's butt on the red carpet during ET's interview with the designer.

Pink -- another surprise performer at the event -- struck a fierce pose in an orange maxi dress, which she sported underneath a white blazer. The singer was joined by her husband, Carey Hart, and was quite the social butterfly at the bash, our source notes, chatting with partygoers including Bloom, Manson, Quincy Jones, and American Crime Story star Selma Blair.

A glowing Chelsea Handler proudly showed off her new fit physique at the festivities, sticking close to fellow comedian Silverman, who went casual in jeans under a black blazer.
