Black Eyed Peas star parties with The X Factor judge at Cannes Film Festival
Cheryl, 26, was paid a whopping £250,000 for the 30-minute show – in which she sang 6 songs – by organisers de Grisogono.
After the gig, Will.i.am hit the decks for a DJ set.
Cheryl joined him in the booth and they were seen kissing on the cheeks as they greeted one another.
She split from footballer husband Ashley, 29, in February following allegations he cheated on her.
