Much like Dua Lipa before her, Billie Eilish is currently living her best life on vacation. The singer has been hanging with friends in Barcelona, and was just spotted taking a nighttime dip in the water while wearing a red string bikini. FYI, the Daily Mail has the pics!

Billie's Barcelona trip comes just days after she was spotted in Venice all-but confirming her relationship with Nat Wolff by kissing him on a balcony.

A source told the Daily Mail shortly after that "the relationship between Nat and Billie was a long time coming. It was based on an initial friendship from years ago and a trust that turned romantic and they couldn't ignore the chemistry, with both diving in headfirst. They hang out loads, they have toured with each other, vacationed together and he's been in her music videos. Becoming a couple was the next logical step. They are both very close to their families which is one big reason why they work. They're almost the same person and have many similarities." The insider added that Billie "doesn't have the worry that Nat is out for fame, as he already has his own."

Billie and Nat met back in 2023, became fast friends, and before long Nat starred in Billie's video for "CHIHIRO." He and his brother Alex then opened for Billie during the Hit Me Hard and Soft tour, relationship rumors started heating up in March, and they've been vibing ever since!
