Billie Eilish, Nat Wolff Date Night

Nat Wolff and Billie Eilish proved they’re birds of a feather.

Seven months after confirming their romance, the Paper Towns actor was on hand to celebrate Billie at the 2026 Grammy Awards at the Crypto.com Arena in Los Angeles Feb. 1 as she picked up the award for Song of the Year and is nominated for Record of the Year and won Song of the Year. 

While Billie was shocked about her win, she and Nat shared a sweet embrace as he kissed her head before she made her way to the stage with brother FINNEAS to accept their award.

Nat, 31, and Billie, 24, first connected in March 2023, attending a dinner alongside Nat’s brother Alex Wolff, with whom he plays in the band Nat & Alex Wolff (formerly the Naked Brothers Band). While the two danced around dating rumors, they finally confirmed they were together when they stepped out for a PDA-filled outing in Venice in June.

And the couple doesn’t just share a personal relationship, but a working one as well, with Nat and Alex opening for Billie in 2024 during her Hit Me hard and Soft tour. She also served as producer on the album cut of their song “Soft Kissing Hour.”
