Fergie and Josh Duhamel
Fergie's husband Josh Duhamel watches her get bikini waxes.
The 39-year-old singer has revealed the 42-year-old actor - who she married in 2009 - occasionally walks into the room when she is going through the personal grooming session but instead of walking back out again he likes to stick around because he is "curious" about the process.
She said: "I mean, he's walked in on me during my bikini waxing, and I'm like, 'OK honey, hi.' And I'm on all fours, but he doesn't just leave; he gets curious."
The blonde beauty also admitted Josh doesn't have any issues joining her for couple's therapy sessions.
She explained: "He's not afraid. He doesn't feel like he's not man enough."
The couple have 16-month-old son Axl together and have made plans about how to juggle their careers to make sure they see as much of each other and their child as they possibly can.
Speaking in the new issue of Allure magazine, she added: "My husband and I made a two-week rule. We've already talked about how we're going to have to trade off.
"He's going to have to come on tour with Axl for a while, and then there'll be a break. He'll take a job; I'll be on set with Axl."
Fergie's full interview appears in Allure magazine's February 2015 issue.
