Although Kandi Burruss got her fame in the R&B group Xscape, she is also well known for creating some of the biggest hits of other iconic girl groups. TLC’s “No Scrubs” and Destiny’s Child’s “Bills Bills Bills” are songs Burruss crafted for the groups which became monstrous hits. The song would get Destiny’s Child two Grammy Award nominations for Best R&B Song and Best R&B Performance by a Duo or Group With Vocals. The singer and Real Housewives of Atlanta star gave some insight into how she came up with the idea of one of Destiny’s Child’s top charting songs.

In a recent interview with Glamour, Burruss  shared five unknown facts about five songs that she wrote, including “Bills, Bills, Bills” from Destiny’s Child’s sophomore studio album The Writing’s on the Wall.

The lead single of the album was also written by She’kspere and Destiny’s Child, and Burruss told the magazine that she pulled from her real-life experience to help pen the track. “When I got with the girls at the studio, we were singing them the idea,” said Burruss. “I had the melody of how I felt like the verse should go, and we came together for the lyrics.”

“I use a lot of my past relationships as inspiration. The relationship I had been in prior to [writing the song], I took inspiration from it…though I didn’t tell them that,” she continued. “Now, this is the really funny part: One of the girls that was in the group was dating my ex at the time. So I didn’t tell them that some of the lyrics in there were inspired by him.”

“The part that was a clear inspiration—using my phone and pretending like he didn’t use it, driving my car and not putting any gas in it—that was real stuff that had happened to me!” However, Burruss refused to give any details regarding who the man might be, leaving fans to speculate about his identity.
