Many celebrities attended Billy Eilish's Halloween party on Saturday, October 26. Kaia Gerber surprised everyone by hiding her potential Halloween costume in a stylish black blazer.

A hint of a navy pleated skirt and tie seemed to peek out from underneath, but it was Gerber's sleek blazer that caught the attention. She paired the jacket with black riding boots and carried a black Celine bag.

Céline remains one of Gerber's favorite brands, and she was the face of its first Pilates collection. She is also often seen with a Céline bag, whether she is going to a book reading or keeping it casual with her ballet shoes.

Also in attendance at Eilish's Halloween party were Phineas and his girlfriend Claudia Sulewski, Sasha and Malia Obama, and Kiernan Shipka.

It makes sense that Garber, who grew up as Cindy Crawford's daughter, began her career as a model. In recent years, Garber has also ventured into acting, surprising fans with her talents on shows such as “Palm Royale” and “American Horror Story” and in films such as “Bottoms” and “Babylon.”

In an interview with ELLE U.K. in December 2023 has spoken about her passion for acting. I did acting in school before I started modeling, and it made my naturally shy personality a little more outgoing,” she said. It made me more comfortable being around people.”

Gerber, who now has both careers concurrently, reflected on how each talent affects the other. 'With modeling, I learned the power of transformation,' she told the outlet. 'When I resumed acting, I had to completely forget that the camera was there. But I think they both go hand in hand.”

Gerber also made it clear that she is serious about building an acting career. 'Acting has always been my passion, though,' she told the magazine. I feel fulfilled and I want to keep doing it. I can't believe how lucky and fortunate I am.

Referring to the thrill she felt working alongside Laura Dern and Kristen Wiig on Apple TV+'s “Palm Royale,” Garber said, “I was on set with my eyes wide open and couldn't believe I was there. I learned so much working with them. I hope everyone likes it."[17
