Evan recentlytold PEOPLEthat his wife and mother have a very close relationship, with the icon even sitting front and center for the July 2015 birth of his daughterJagger Snow.

The trio has previously worked together, appearing in the 2014 music video for Evan’s song “How to Live Alone.”

“[My mom] comes into the studio and helps me. She’s so good at it, and she’s been doing it so long. And she’s such a perfectionist,” Evan told PEOPLE of the legendary Supremes singer. “Sometimes I’ll be like, ‘Let me have a few practices before she comes in to hear it.’ ”

When it comes to his mom, “a lot of people are like, ‘That’s Diana’s son, what is he going to do?’ There’s always been a lot of pressure,” he said. “But at the same time, you’ve got to do your own thing. I’m pretty positive Ashlee enjoys my singing, at least most of the time. We sing together all the time, we’re so close.”

Ashlee + Evanpremieres Sept. 9 on E!.
