Nicole Scherzinger says she has created "a monster" after helping X Factor flop Rylan Clark find fame.
The fake-tanned reality star came fifth in last year's X Factor despite his eccentric singing style, and won the last Celebrity Big Brother.
Nicole, who mentored Rylan on the X Factor, said she had been snubbed by him recently.
Appearing on tonight's Jonathan Ross show, she said: "I've reached out to Rylan a few times. He had that show and I tweeted about him, wanted people to vote for him.
"He must be really busy because I've tried to hit him up a couple of times, and I was like, 'hey come to my show this weekend, G-A-Y' and he's like, 'sorry, got a gig in Ireland'.
"Then I hit him up before and he's kind of an Essex diva. I've created a monster. I even sent him, I found a pair of gorgeous sparkly balls, cufflinks. I was like, 'these are perfect for Rylan.' So I gave them to him for Christmas and I never even heard back."
The former Pussycat Doll said she was not sure if she would return to the hit talent search show for the next series.
She said: "I don't know, it's up in the air. I would tickle with the idea, as I like to say."
She said her boyfriend, racing driver Lewis Hamilton, was so interested in music he had built a studio in their home in the US. She said: "He told everybody he's putting it in for me and I haven't got to use it yet. He plays the guitar and drums, he is pretty talented. He has a beautiful singing voice. He's doing his own music, I'm just there to support him."
