The Pussycat Dolls star paired this with flared check trousers and boosted her height with black silver tip heels.

Nicole was at the London venue to make a guest appearance during Rylan Clark's Children In Need fundraising challenge.

Rylan will attempt to sing dozens of popular hits for 24 hours straight and started his singathon at 9.15am on Tuesday. 

A host of famous faces have got involved with the reality star's challenge including Claudia Winkleman and Rick Astley. 

Nicole's appearance comes after she joined Simon Cowell's partner Lauren Silverman for an evening out at the exclusive Arts Club in Mayfair on Monday.

Sporting a multi-tiered floral print dress, Nicole caught the eye as she exited the club and she accessorized with a wide-brimmed hat and black suede boots.  

Nicole was stepping out little more than a week after making the controversial decision to save one of rival X Factor judge Simon's acts, instead of one of her own.

The singer was accused of breaking the rules for saving Try Star - made up of rugby stars Thom Evans, Ben Foden and Levi Davis - but she has since insisted it was the right decision.

She told The Jonathan Ross Show: 'I like to break the rules. The song [they sang, "Swing Low"] has a very deep meaning in America, it’s an old black spiritual and so I just thought it was a beautiful song.

'But then I did some research and I understand that it’s the rugby anthem. I don’t know the sport very well but I love the camaraderie and the fight and the spirit and the heart.'

All for a good cause: Nicole took part in Rylan Clark's ka-RY-oke challenge where he will sing for 24 hours along with a host of famous faces to raise money for Children In Need

While on the talk show Nicole also spoke about the possibility of a Pussycat Dolls reunion, saying: 'I can't confirm anything right now but I wouldn’t rule it out. We are talking.'

Asked if talking meant there was a good chance of a reunion, she added:  'Yes. We haven't talked in many years so we are talking now.' 

The band split in 2010 and had a hugely successful seven-year career, during which they sold more than 54 million records worldwide.
