Billie Eilish seems to have found her stride in Hollywood. The 20-year-old Oscar and Grammy winner was seen arriving at supermodel Kaia Gerber’s 21st birthday party in Los Angeles on Saturday night (September 3). 

Making a statement fit for a rock star, Billie attended the A-list gathering in a sleek white zip-up top, a black mini skirt, and matching thigh-high leather boots.

The “Bad Guy” singer appeared to be flying solo at the event following her recent breakup with boyfriend Matthew Tyler Vorce. The 30-year-old actor, however, dismissed rumors of infidelity. Taking to Instagram stories, he clarified, “Nobody cheated on anyone. Relationships end. Simple as that. Creating rumors and LYING on the internet is dangerous.”

In another Instagram slide, he expressed, “The fact that thousands of people take time out of their day to write the most heinous things on someone they will never know’s posts is the most cowardly thing you can possibly do. Live your own life.”

Their whirlwind romance, which began in April 2021, featured PDA-filled walks, trips to Disneyland, and an appearance at Doja Cat’s birthday party. Matthew even accompanied Billie on part of her tour in February of the following year. Despite initial reservations, sources revealed that Billie’s team believed it would be beneficial for him to join the tour to alleviate her strеss.

The insider shared, “He is always extremely polite around her people, and he stays out of the way. He lets Billie always have the spotlight, and the two of them are a good match for each other. At the end of the day, when all is said and done, Billie gets to come home to someone who cares deeply for her and who she loves very much.
