Billie Eilish is in a happier place than ever before, all thanks to her boyfriend. The "Birds of a Feather" singer has shown that her romance with Nat Wolff is still going strong by offering sweet support for his and brother Alex Wolff's new self-titled album, which was released on Jan. 16. In a post shared to her Instagram Story on the same day, Billie reshared the siblings' own post announcing the arrival of their record, which featured a backlit photo of the pair sitting on fold-out chairs. Alongside the snap, the two-time Oscar winner expressed her excitement for the project by writing three exclamation marks.
And that wasn't the only way Billie, 24, shouted out Nat, 31, whom she first confirmed her romance with in June when they were spotted going out in Venice in a PDA-filled outing. The "Ocean Eyes" singer also included a snippet of the Nat & Alex Wolff track "Midnight Song" on her story.
Of course, Billie has shown her support for Nat and Alex's music outside of social media as well. In addition to inviting them to open for her on her Hit Me Hard and Soft Tour, Billie served as a producer on The Naked Brothers Band alums' album cut "Soft Kissing Hour."
"When we did the song with Billie, it was so homegrown," Nat told Rolling Stone in an interview published on Jan. 16. "It was just the three of us in a room. We had one mic, and I was holding it because we couldn’t reach it to the piano, where Alex was playing 20 feet away."
And the Paper Towns actor also credited Billie—who previously joined forces with the musicians on her 2024 song "Wildflower"—with suggesting she contribute background vocals to the outro of the track.
"It was Billie’s idea for her and I to sing in that section [at the end of the song]," Nat explained. "She was like, 'Oh, it’s a beautiful thing to do. We did it on "Wildflower."'"
In an adorable turn of events, Billie's dog Shark wound up sneaking onto the recording as well. As Nat explained, "When we sent it to the mixer, he took out little bits of audio, like Billie’s dog snoring and we went, 'Actually, can you put those back in?'"
"Something about that was inspiring," he continued. "I was like, 'Oh, if you don’t have all the time in the world and all the equipment and you’re kind of running gun and feeling like it’s just play, there’s something magical that can come out of that.'"
