Carol Vorderman has sparked concern after she appeared on The One Show looking very different from her usual glam self.
Carol had recorded a special video for the show, talking about her love of flying. She spoke about how she'd qualified as a pilot a while ago, and was seen flying a small plane.
And she even added that she was going to attempt to fly a loop the loop for viewers of The One Show! Her amazing stunt required her flying at 165mph - she's braver than us!
What's happened to Carol Vorderman's face?
But as she talked about her passion for taking to the sky, it wasn't her airborne antics that attracted attention - it was her face.
Fans took to social media after the show to share their concern about the former Countdown star's odd appearance.
One viewer wrote: "Oh my. What has Carol Vorderman done to her face?" and another wondered: "What's happened to Carol Vorderman's face?"
Another fan joked: "Very unfair of @BBCTheOneShow to make Carol Vorderman film this piece while suffering from the mumps."
And one critical viewer even speculated about what had made Vorders look that way. "It it reasonable to assume that Carol Vorderman has 'had work done'?" he wrote.
"What has Carol Vorderman done to herself? Sad how an intelligent, successful woman feels obliged to butcher her face?" said another.
But it wasn't all bad. Lots of fans were wowed by 56-year-old Carol's skills in the cockpit.
"Great loop the loop on The One Show last night," one impressed viewer tweeted.
