The three blondes bumped into another star, actress Sienna Miller on their night out. "I met the gorgeous Sienna Miller, she's a top girl.. love her," tweeted Nicole.
The singer, who was recently a guest judge on The X Factor, gave updates of her evening. "So far so good!! Xxx " she tweeted, alongside a smiling photo of herself, Holly and Emma. She soon followed this with another photo of the trio entitled "The blonds!!!!"
"It was such a good night," she wrote in a tweet to a friend the next day.
Emma was up bright and early next morning to present the Heart FM breakfast radio show with Jamie Theakston, who coincidentally is former boyfriend of Nicole.
In September, Nicole and Holly were joined by more girlfriends including Nicole’s former bandmate Melanie Blatt as they enjoyed a sunshine break in Ibiza.
"@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.
