X Factor 2011: What rivalry? Kelly Rowland praises 'great mentor' Tulisa!

Tulisa and Kelly

Despite claims of backstage arguments between them, Kelly Rowland had only good words to say about Tulisa this week, after the N-Dubz star lost her second of four acts from the show. Despite Nu vibe being voted out on Sunday night, Kelly praised Tulisa's mentoring of the groups category.

Speaking on Xtra Factor to Olly Murs and Caroline Flack, Kelly said: "Can I just say what a great mentor Tulisa is?

"She has really whooped these groups into great shape and I think she really deserves a great round of applause from everybody."

Louis Walsh agreed, adding: "She works so hard, she put three acts together, she formed these acts and she’s worked really, really hard and I think the two acts she has left are amazing."

Meanwhile Nu vibe, who lost out to Frankie Cocozza in Sunday night's showdown, told This Morning they couln't have wished for a better mentor.

"We’re grateful to have had this experience and to have met her, because she’s an amazing mentor," they said.

The group, who have vowed to stick together despite their exit, added: “She was always round the house, cooking for us all, sitting down with each group and getting to know us all.”
