On Saturday night (Oct. 26), a lucky few were treated to an acoustic set from Billie Eilish at UNICEF's annual Masquerade Ball in Los Angeles. The crowd at the Kimpton La Peer Hotel was nowhere near as big as the ones Eilish has been playing to lately, but lucky for us, footage of the performance recently popped up online.
As NME points out, a fan on YouTube posted a mash-up of highlights from the evening, including Eilish arriving on the red carpet and performing acoustic versions of songs like "Bad Guy" and "When the Party's Over." Eilish also shouted out her music/fashion inspiration (and apparent new friend) Avril Lavigne after learning she was in attendance ( video below, see her tell a little story about why she happened to be wearing the same pants as Avril).
The Billie show was part of an event for UNICEF Next Generation, a subdivision of the humanitarian organization that focuses on young adults and their efforts to improve the lives of young children.
Eilish then took to Instagram on Monday (Oct. 28) to share an epic pic of her squad — including brother Finneas, actor Jameela Jamil and singer-songwriter James Blake — visiting Halloween Horror Nights at Universal Studios. "Thank you @horrornights for the amaaaazing treatment last night…i cant tell you how much fun we had," she wrote.
