"I got an email from her team saying they've got an availability," he said, adding that, unfortunately, he wasn't in LA to take the job. "That was the moment where I was like, 'If I don't make myself available, it's not going to happen.' So that's when I moved to Hollywood."
Still, "for the first week, I didn't do anything; I didn't work and I thought, Oh my God. What have I done? I gave up my home, my life in England. I was just sitting there in LA twiddling my thumbs. I'm a worker, I like to work, so it was strange for me. Then, I got the call from Christina Aguilera's team to do her for The Voice."
After that, all bets were off — and Appleton was booking back-to-backs with everyone from Katy Perry to Adele to Ariana Grande to Kim Kardashian. Then, a moment with Lopez came full circle.
I got an email from [J Lo's] team saying they've got an availability. That's when I moved to Hollywood.
"Before I met J Lo for the first time, we had a call for the Ain't Your Mama music video, and she got on the phone and was like, 'Hey baby, we're going to do sixes and then we need to change, and it will be really fast paced.' I don't even remember everything she said; I was just trying to figure out if I should call her J Lo or Jen or Jenny from the Block," he laughed. "When I met her, she told me she had her eye on me for a while. I don't get starstruck — I believe people are people — but that's about as close as I get. It felt quite like winning the lottery, in a way."
