Considering that Nicole Scherzinger swooped on Cheryl Cole's X Factor USA job following her infamous axing last year, you'd be forgiven for thinking the two weren't exactly the best of pals.
However, they proved there were no hard feelings last night when Nicole turned up to Cheryl's official tour after party, which she hosted at London's Whisky Mist, following her performance at The O2 Arena.
Nicole, who is now a judge on the UK version of the show where Cheryl made a name for herself, popped along to the celebrations in the same gold dress she wore on Sunday night's show, which saw the controversial elimination of Carolynne Poole.
She was even seen cosying up to Cheryl's BFF and manager Will.i.am, who had joined her on stage earlier in the evening.
Cheryl's current beau, Tre Holloway was by her side all night but there were some other very special guests in the shape of her Girls Aloud bandmates Nicola Roberts and Kimberley Walsh.
The ladies had been down at the O2 to support their chum and had hotfooted it across town to join the party.
During the night, Nicola posted this snap of the three of them cosied up together alongside the caption: "
The trio are set to reunite with other members Sarah Harding and Nadine Coyle as part of their 10th anniversary celebrations next month.
According to today's Daily Star, they are set to make a comeback performance on Strictly Come Dancing, where Kimberley is currently competing.
A source told the paper Cheryl is especially excited about appearing on the show that rivals The X Factor.
“It’s an amazing slap in the face for Simon (Cowell) and proves that Cheryl really wants Strictly to beat her old show,” they said.
