Kelly quit after just one series on the prorgamme, and Tulisa didn't hold back in an interview about her fellow judges past and present today!
Speaking to Radio 1, Tulisa said: "I've enjoyed having different people."
And her favourite guest judge? Tulisa replied: "Mel B is Queen Bee. I LOVE her. I love her I love her I love her."
She continued to gush: "And Louis is looking good at the moment. His hair! He's um, rejuvenated himself."
"He's very lovable. He's always laying into me. He likes winding me up, because he knows I'll react to it. But it's just banter."
On Nicole, Tulisa continued: "She's LOVELY. When she's on stage performing, the queen bee just comes out. But on a day-to-day basis she's quite relaxed and quite a reserved character."
However when it came to Kelly Rowland, Tulisa was less to talk.
"Ummmmmmmmmmmmmmmmmmmmm," she said when asked if she missed the US star, adding: "Um. No comment."
"I'll take that as a no, then," replied DJ Sara Cox as Tulisa remained silent on the subject.
Meanwhile, in a lot less serious news, Tulisa revealed just why she decided to dye her hair blonde.
"I just woke up one morning and fancied a change and went blonde and then I woke up the next and fancied brunette," she explained."When I was a kid it was literally blonde, and then I went darker. So yeah, I guess it's naturally like this."
"The Greek side of my family are actually all really fair."
