The X Factor judge stood out from the crowd in a scarlet wraparound dress at a private dinner organised by Sony Music in London on Tuesday night (4 February).
Although, we reckon she'd probably turn heads even if she arrived in jeans and a hoodie…
Nicole, 35, jetted into the UK earlier this week from Los Angeles.
There's no word yet on what she's working on over here but we're guessing it's her upcoming fashion collaboration with Missguided.co.uk. Nicole's 30-piece range will include dresses, jumpsuits, skirts, tops and bodysuits.
"I'm so excited to be collaborating with Missguided!" she said. "I've worn their clothes in the past, as I'm a big fan! This is my first time designing my own collection and I can't imagine a more perfect fit than Missguided."
We've been missing our weekly fix of Nicole following the X Factor finale in December, which saw Sam Bailey win over teenager Nicholas McDonald.
X Factor (as always) hasn't confirmed the judges for the upcoming series, although newspaper reports have claimed Simon Cowell is eager for Nicole to return.
If she does, she'll certainly have a busy year ahead of her with her fashion collaboration, X Factor and a promise to fans that she'll have new music soon.
During an interview on Xtra Factor in December 2013, she said fans would hear new music this year, and she later shared pictures of herself "making magic" in the recording studio. Her last single was 'Boomerang', back in 2013.
