The Friends star is so embarrassed little Coco's play date with another celebrity tot turned wrong, she refuses to name the Academy Award-winning actress whose offspring was infected.
She explains, "I look over and she (Coco) is itching her hair... I was so panicked, so I called her (the actress) up and I was like, 'Guess what? We're either going to be the best of friends, or you're never going to talk to me again.' And I said, Coco did in fact have lice.' She said, 'Oh, it's just a right of passage.' She was so sweet."
But the incident turned from bad to worse when Cox realised her own head had been infested by the bugs.
She adds, "I got it and it isn't so funny anymore - especially when the paparazzi follow you (into the hair salon)."
