SZA shared some heartbreaking news with her fans during her show at London's O2 Arena.

"I never told anybody, but like, my boyfriend cheated on me in this city before," the "Kill Bill" hitmaker revealed in between songs.

"It was terrible. That's why I was really sad to come here, but you guys made it so much better. Thank you! This song is about my other trash ex-boyfriend," she added before performing "Nobody Gets Me."

SZA once talked about how her newest chart-topping album, despite being full of banger hits, was inspired by loneliness.

"Originally I was supposed to be on top of a shipping barge, but in the references that I pulled for that, I pulled the Diana reference," the singer explained about her album's cover, referring to the late Princess Diana.

"Because I just loved how she isolated she felt, and that was what I wanted to convey the most."

SZA Calls Out Her Exes

This is not the first time SZA has called out an ex-boyfriend onstage. In fact, just a month ago, she candidly talks about an ex during her Portland show.

Apparently, the ex blocked her on his phone, which only set her off even further. "My ex's father just texted me and was like, 'My son is really hurt about what you said about him to the crowd.'"

"You don't get to block me on everything. Tell our mutual friends terrible things about me like I'm a monster, or whatever the case may be. And then I don't get to speak my piece in my way. You go do your healing and I'll do mine."

SZA's Ex Who Inspired 'Nobody Gets Me'

According to reports, one of SZA's most heartbreaking and devastating songs, "Nobody Gets Me" is about an ex-fiance.

"This particular song in entirety is a story about my ex-fiancé and how we went through all these arguments, and we broke up," she said then explained how terrible it felt when they first broke up, because he was such a great support system.

"He was just this rock in my life that just no longer exists. The stories that I tell in that song about our arguments... That's the theme on that. I feel like a lot of people don't understand me, but it's okay."
