The Geordie star was joined by her Girls Aloud bandmate Nicola Roberts, her PA/BFF Lily London, brother Garry Tweedy and musician friend Joel Compass.
Nicola posted a photo of the group where, along with lots of glasses of red wine, Cheryl can be seen giving singer Joel an air kiss!
Alongside the pic, Nicola wrote: "A kiss for @joelcompass .. Lovely dinner with @ladyccole @garrytweedy @iamlil <3 xo."
Joel is good friends with Nicola - he's been working closely on her solo music and the pair have even written a song together.
Cheryl confirmed her return to X Factor on Monday night (10 March), and appeared alongside Simon Cowell at a press conference in London today, showing off her newly-dyed blonde hair.
She left the show back in 2011 to join Simon on the US X Factor, but was axed from her judging role just a few days into filming.
