At 44, Courteney Cox can still pass for a supermodel–too bad it’s Janice Dickinson!

The former Friends star was left seething after a group of teenage girls mistook her for the super bitchy catwalk creature on the Seal Beach, California set of her upcoming series, Cougar Town.

Star writes: “A group of teenagers approached Courteney between takes and asked her about America’s Next Top Model” says the source. Janice, 54, used to appear on the show as a judge. “She was pretty upset and coolly told the girls they had the wrong person!”

A shaken Courteney immediately phoned her husband, David Arquette, for reassurance that she is much prettier than the 54-year-old former model.
