SiCo: Cheryl Wags Her Tail When Working For Me
The X Factor boss claims returning judge is like a happy puppy...
And quick as a flash, SiCo shot back: "She loves working with me, if she had a tail she'd wag it."
The show supremo and pop star Chezza enjoyed a double date together at the event, joined by their respective spouses Lauren Silverman and Jean-Bernard Fernandez Versini.
And he also talked up his own chances in this year's show - in which he is mentoring the over 25s.
"I'm very confident," he said. "I've got three great people. I'm going down to meet them all tomorrow, have a little chat with them, bit of a pep talk before Saturday so everyone's prepared. It's going to be good."
Chezza impressed fashion fans with her blue lace Michael Costello dress.
