Nicole Scherzinger admits she was shocked to be axed from The X Factor USA but has "no regrets."

The singer, along with host Steve Jones and fellow judge Paula Abdul, have not invited back for the second season of the show.

Nicole has told Access Hollywood that she gave the role her best but is now focusing on moving forward.

"Well, all I know is that I gave 110 percent to that show," Nicole explained.

"I know everybody's talking about it, they're saying good, bad, they love me or hate me, but the one thing you can't say is that I didn't give it my all.

"I had a wonderful experience on the show. I loved being a part of my X Factor family. Nothing could obviously prepare me for everything I had to go through, all the emotions and stuff, but I have no regrets.

"I've always believed in never looking back and just moving forward and I've got an amazing year to look forward to."

Nicole will be heading out on a European tour to support her new album Killer Love, and she wants to try her hand at some more musical theatre.

The former Pussycat Doll also has a role in Will Smith's upcoming movie, Men in Black 3.

Meanwhile, Simon Cowell has denied that he's offered Beyonc Knowles a multi-million dollar contract to sign up as a judge.

"I have no clue where that came from," he told Extra TV. "I read that online that I offered her $100 million a year. The budget for the show is $100 million. That would never, ever happen. It's absolute nonsense."
