Nicole, 38, headed off on a girls' trip to Ibiza with This Morning presenter Holly Willoughby and her fellow All Saints bandmate Melanie Blatt, among other friends.
The pop singer looked to be enjoying the Spanish sun and the company of her girlfriends, and took to Twitter to document her weekend.

"@melblatt @shiarra @hollywills @lizmendez1 Ibiza!!!!! Xxxxx," wrote an excited Nicole, next to an image of the group having drinks alfresco.
"Ahhhh @hollywills ❤❤❤," she later tweeted, alongside a photo of her and Holly.
The television host was quick to post a snapshot in return, again of the blonde duo smiling away and having a whale of a time.
"Beautiful times, beautiful friends...," tweeted Holly.
Nicole and her friends returned to London today, with the Canadian singer posting, "And after an amazing weekend...it's time to go home @hollywills @shiarra."
The mother-of-one is reportedly close to finalising a £10million divorce settlement with her husband of five years Liam.
The Beady Eye singer is said to be keen for a quick divorce, as his new girlfriend Debbie Gwyther has reportedly moved in to his North London home, just around the corner from Nicole.
The songstress, meanwhile, has been keeping herself busy and is working with Louis Walsh as a guest judge on The X Factor.
