Speaking to Reveal at the Inside Soap Awards, the Hollyoaks actress declared that she finds the comparison to the Girl's Aloud star "flattering".
Shenton, who plays Mitzeee on the Channel 4 teen soap, divulged: "I have been told a few times that I look like Cheryl Cole.
"I'm sure she hasn't got a clue who I am, but it is flattering. She's really hot, so it's great!"
Cole recently took an interest in Hollyoaks Later, the show's late-night spinoff, due to the fact her bandmate Kimberley Walsh's sister Amy appeared.
Shenton also played a part in the special week-long series, which was screened on E4 earlier this month.
The 24-year-old has declared her delight with her character's new looks since being jailed. Mitzeee was falsely accused of stabbing rival Mercedes McQueen.
"My character is going through a tough time and isn't wearing make-up at the moment and I love it," the soap star added.
"I get in to work, they whack a bit of under-eye cream on to make me look like I've had no sleep, so it takes 5 minutes. It's brilliant!"
Shenton confirmed last year that she prefers not to wear make-up off screen.
