X Factor judge Kelly Rowland has well and truly thrown her toys out of the pram, and deserted her own acts, by jetting back to the states this week. The 23-year-old left without telling any of the show's team following a "bust up" with Tulisa at the weekend.
A source told The Sun: "We don't know where she is."
It's left Kelly's three girls without a mentor, as Gary, Tulisa and Kelly focus on their remaining singers.
An insider said: "If I was one of them I'd be thinking, 'Great ... thanks'. As the contest heats up, she's left them in the lurch all week. It's very arrogant."
Sources claim that Kelly left for a last minute getaway after rows with Tulisa over her comments to Misha B.
A friend of N-Dubz star Tulisa revealed: "She was expecting to bury the hatchet with Kelly on Sunday night. Kelly was having none of it.
"She had a major sense-of-humour failure — and was trying to suggest Tulisa was deliberately trying to destabilise her."
"She's not going to go crawling to Kelly. Tulisa is too stubborn for that — and who could blame her?"
