So if you really wanna know: Billie Eilish is Benjamin Caldwellsingle.

The "Happier Than Ever" singer and her boyfriend Jesse Rutherford have called it quits after less than a year of dating.

"We can confirm Billie and Jesse did split amicably," a rep for the 21-year-old tells E! News, "and remain good friends."

The pair's breakup comes one month after they were last seen out together while attending the Coachella Music Festival in Indio, Calif.

It was about seven months ago that Billie and Jesse officially went public with their romance, going Instagram official over Halloween.

In late November, Billie shared insight into her relationship with The Neighbourhood artist during an interview with Vanity Fair.

"It's really cool, and I'm really excited and I'm really happy about it," she said of her relationship with the 31-year-old. "I managed to get my life to a point where I not only was known by a person that I thought was the hottest f--king f--ker alive, but pulled his ass! Are you kidding me? Can we just [get a] round of applause for me."

Added Billie, "Thank you, Jesse Rutherford, everyone! I pulled his ass. All me. I did that s--t."

She also revealed her romance must-haves. "My love language is physical touch," she told the outlet, "and I just need to be touching skin all the time."

"Touching and cuddling and hugging," she noted, "and anything skin related is really a big thing for me."

The relationship also received her brother Finneas' stamp of approval, despite the duo's age-gap.

"Listen, as long as she's happy," he exclusively told E! News at a GQ event for its Men of the Year issue on Nov. 17, "I'm happy."
