Cheryl joined the X Factor audience on Saturday night as her boyfriend Liam Payne returned to the stage where he first found fame.
The former One Direction star appeared on the show for the first time as a solo artist, and was supported by Cheryl, who was previously a judge.
She sent a message to the absent Simon Cowell, who is resting at home after suffering a fall on Friday.
“First of all I really miss you, Simon, I know you’ll be watching at home, you’re very, very missed and we love you,” she said.
