The 'Boomerang' singer posted a couple of photos to Instagram showing the luxurious gold-themed room she's been staying in with pals.
Nicole, 35, hasn't said why she's in Dubai but as she tweeted a happy birthday to her friend in the first picture, we're guessing it's a girly holiday in the sunshine.
While she's enjoying time with her besties, other half Lewis Hamilton is over in Melbourne preparing for the Australian Grand Prix.
Lewis recently took their on-off relationship public again by posting a photograph of him and Nicole at the Sistine Chapel.
He added the caption: "This was a great day… truly humbled by the Sistine Chapel plus there with my wifey #godisthegreatest #sistinechapel #blessed."
It's thought the photo was taken while the couple celebrated Valentine's Day together in Italy last month. There had previously been pictures floating around of them meeting Pope Francis.
Nicole, meanwhile, has left her judging role on X Factor but has plenty of projects in the pipeline, including her new album (yay!) and a fashion collection with Missguided.
