There's a good reason."Well, that's because I got fired," Gage said. "I walk on set, I see Kiernan Shipka, who's now one of my best friends, and they [the crew] see this giant tattoo on the whole side of my body while I'm going to be shirtless, playing a 15-year-old in the 50s."It wasn't working, all odds were against me," he added.When Ripa asked if they could cover it with makeup, Gage said, "It wasn't gonna work," and that they "recast it real quick.""It was like one of the first jobs I got, I bragged to everyone about it, and then they said, 'You're going home," he said. "But, if I didn't book that job, I wouldn't have booked the next couple things. Everything led to the right place."Gage said that he and Shipka now laugh about it, and she calls him "Tattoo Boy." He then shared a heartwarming story about when Mad Men star Jon Hamm spotted Gage catering at the Emmys the following year."He remembered me and gave me a hug, and said, "Everyone has to get fired once in their career."Watch Lukas Gages full interview on LIVE with Kelly and Mark below.
