Jenny McCarthy and Donnie Wahlberg chat with ET’s Kevin Frazier about the New Kids on the Block singer’s shocking reveal as Cluedle-Doo on ‘The Masked Singer,’ airing on Fox. McCarthy reacts to how she fell to the ground upon seeing her husband onstage. She says, ‘I was shaking for about an hour.’ Wahlberg says his costume helped prevent McCarthy from picking up on his signature dance moves. He jokes that performing on the show was like being a walk-around character at Disneyland. In order to keep his role a secret, Wahlberg even dressed up like his ‘Blue Bloods’ character to pretend he was on set on the police drama when video chatting with McCarthy!
