Levine previously spoke to PEOPLE about his “big opening night in Vegas” and how his family played an important part in his decision to take on the residency.

“It’s close to home and no one has to deal with, you know, traveling 10 hours with kids and jet lag,” said Levine. “It felt right. It felt really, really sweet to have everybody here. I wouldn’t have wanted to do it without them.”
