George, who was runner-up on I'm A Celebrity...Get Me Out Of Here!, wore a cosy brown knit as he made his way to the London venue.
The boyband star didn't have a quiet entrance, however, as he was stopped by fans wanting to grab a selfie with him!
His trip to the studios comes as he and a slew of celebrities are showing their support for ITV's Text Santa and Christmas Jumper Day.
Earlier this week, George compared his romance with campmate and TOWIE star Ferne McCann to that of Caroline Flack and Olly Murs.
After admitting that they've already shared a "drunken kiss" following their flirting in the jungle, George said he and Ferne won't be rushing into anything.
George told the Daily Star: "We have a really unique relationship... I'm not sure if it's a Caroline and Olly sort of relationship and the secret to their success is they've never slept together."
"We are just going to take it slow and see what happens. We did have a drunken kiss but that's all for now."
On Wednesday, George said he was missing his "parter in crime" Ferne following a joint radio interview.
