When Brit Brit's not slaying onstage, she's spending time with her rumored new boyfriend, Sam Asghari.

The singer opened up about the fitness model for the first time during a radio interview on CBS Radio's "Fast in the Morning with Nathan Fast" on AMP 103.7 Dallas on Thursday.

"It wasn't even a serious thing," Spears said of how she met Asghari while filming her music video for "Slumber Party." "It was one of those things that we were having a conversation to get through the experience, you know?"

"I kept his number, and it was so weird -- it was like five months later, and I found his number in my bag. I was like, 'He is really cute. This guy is really cute.' So then I called him, and ever since then, he is just a really fun, funny person," she added.
