Well, the news quickly got to Billie who talked about teaming up with the band during an interview with NPR at the Austin City Limits festival.
Well, it didn't go down that well with some fans... and she wasn't HAVING IT.
In the clip, Billie asked her fans if she should do the collab. Most yelled 'yes' while others yelled 'no!'.
"Stop! Oh, my God, that is so mean," Billie said. "They're very nice. They've said some very nice things about me."
If you're excited about the potential collab with BTS, the "Bad Guy" singer recently made fans believe a collaboration with Camila Cabello was happening.
Billie and Camilla met when they were doing their photoshoot for Elle magazine's 'Women in Music' issue, and had the opportunity to 'hang out' between interviews.
While most people fangirl over Camila's music, Billie couldn't stop obsessing over the 'Senorita' singers perfect facial features.
"She has a perfect nose. She really does. She has a great nose," she told Entertainment Tonight.
Although fans were BEGGING Billie and Camila to unite in the studio, the 'Bad Guy' singer was quick to shut down our hopes and dreams, telling the publication: "No [we're not planning a collaboration]. She just was there and she was nice. It was a shoot we were doing for Elle magazine."
Billie also revealed that when she met Camila, Camila's 14-year-old sister Sofia was there too and promptly sobbed upon meeting our idol, and honestly we can't blame her.
"My sister has never cried, meeting anybody. She’s met Taylor [Swift], my sister’s met everybody, and she literally, fully had tears running down her face. She 100 percent likes her more than she likes me."
