“They are stoked–especially my oldest,” he said. “She’s been doing competitive dance now for the last two years and my youngest is obviously trying to follow in her big sis’s footsteps, so they’re both just elated. It’s going to be awesome for them to watch Daddy cutting a jig on TV.”

He will be joined by “The Bachelorette” star Kaitlyn Bristowe on season 29 of “DWTS”. McLean received words of encouragement from fellow Backstreet Boys member Nick Carter.
