The band's frontman told Parade that he was pleased to see Aguilera take part in a track which is "very different" from her usual solo material.
"It was awesome. She's super talented. I fully trusted her to do her thing. She's a pro. I love how restrained and held back it was. It's very different for her. I loved her delivery," he explained.
Levine also revealed that the success of 'Moves Like Jagger' has added extra enjoyment to Maroon 5's summer tour.
"It's been great. There's so much more buzz now surrounding the record. It's building up again. We're so happy for the success that we've had," he said.
"We kind of had a reintroduction to the world through The Voice and the single 'Moves Like Jagger' is blowing up. Everything is just incredible right now. We're very happy and very fired-up."
