AceShowbiz - Billie Eilish and Nat Wolff may be finding love in each other while bonding over music. The pop star and the actor/musician have been swept in dating speculation following their recent outings, with a source recently confirming their relationship.

The rumors began swirling even before before Nat and his brother Alex Wolff opened for Billie on her "Hit Me Hard and Soft" tour. Further fueling the fire, the two were spotted together at various events and outings. He also starred in Billie's music video for "Chihiro" which was released in June.

While neither Billie nor Nat has spoken up on the nature of their relationship, "a source claiming to have inside knowledge allegedly confirmed that Billie and Nat are indeed an item," according to Deuxmoi. "It's 100% sure," the tipster declared.

The dating rumors come a year after Billie opened up about her sexuality. In an interview with Variety published last December, the Grammy Award winner addressed her previous statement about being "physically attracted" to women. She said, "I didn't (know I was coming out), but I kinda thought, 'Wasn't it obvious?' I didn't realize people didn't know."

"I'm still scared of (women), but I think they're pretty. I saw the article, and I was like, 'Oh, I guess I came out today!' I just don't really believe in (coming out)," the "Bad Guy" hitmaker continued, before adding, "I am for the girls."

Following her confession, Billie was spotted getting flirty with some female celebrities at separate occasions. She, however, has since vowed to keep her private life hidden from the public eye, admitting that she regretted her previous comments on her sexuality. "I wish no one knew anything about my sexuality or anything about my dating life. Ever, ever, ever," she told Vogue in October. "And I hope that they never will again."

Meanwhile, Nat was previously romantically linked to a string of famous beauties, including Margaret Qualley, Suki Waterhouse and Bella Thorne. The 29-year-old actor and nepo baby of actress Polly Draper and jazz pianist Michael Wolff is a close friend of Andrew Garfield.
