The X Factor judge - and fellow Geordie - surprised Tyrese George by recording a message for him congratulating the schoolboy on his scholarship to Eton College.
Cheryl said: "I just wanted to say a massive congratulations to Tyrese for getting a scholarship to Eton. I'm very, very proud of you and I wish you the best of luck!"
Tyrese looked a bit shocked by the message before he responded: "It's very weird to know that she's talking to me and I've heard my name from a celebrity's mouth. That's just so amazing."
Newcastle-based schoolboy Tyrese was joined on the show by his mother Tammy and his best friend Sammy. His mum said she was "over the moon" and felt like the "proudest mum" in the UK.
Meanwhile, loyal friend Sammy said: "I just feel very proud of him because as soon as Tyrese told me he'd be going to Eton I knew he would because it's the intelligence of him and if I encouraged him I knew he wouldn't stop until he gets there. I'm very proud to hear that Eton wanted him and he's in Eton. I know we're going to different schools but I know our friendship will still go on."
