Rowland, 32, is currently busy in promoting her recently-released album "Talk a Good Game" and its first single "Dirty Laundry", reported Ace Showbiz.
Asked by a TV host to name one annoying thing about Beyonce, Rowland, who attended the show to promote her work, said, "She would tell you this. She's a slob. If you walk in -- maybe she's gotten better since becoming a mother -- but she's got a lot on her brain. You can tell she's got a lot going on."
"Dirty Laundry" got everyone's attention when Rowland had revealed earlier that the new song tackled her apparent jealousy over Beyonce's enormous success.
