Scherzinger's act James Arthur was in yesterday's sing-off against Ella Henderson, and the former Pussycat Dolls star introduced the singer as "the effing brilliant James Arthur".

On The Xtra Factor, Olly Murs and Caroline Flack apologised to viewers who may have been offended by Scherzinger's choice of language and the American judge also commented on her passionate choice of phrase.
"I'm so sorry. You spend every day with these people, you spend so much time with them. Ella [Henderson] was the last female in the competition. I was passionate about her as well as James Arthur, who is one of the greatest human talents ever.
"I'm so sorry for my 'effing'."
Arthur survived the sing-off after the judges sent the decision to Deadlock and the public vote decided the final result.
The X Factor continues next weekend with ABBA and Motown themes.
