Josh Duhamel is no stranger to the spotlight, but the ability to blend back in with the crowds still isn’t completely out of the question for the actor.
During a Diet Pepsi event on Friday, Duhamel put it all to the test as he manned the cash register, surprising customers who recognized his famous face.
“It’s an opportunity to really mess with people. There was a lot of people who didn’t [recognize me], but there was enough that did,” Duhamel, 40, told PEOPLE at the I Got a Diet Pepsi And… campaign in Los Angeles.
“I think sometimes the ones who don’t are the best ones. They don’t have a clue and you just strike up conversation and they may recognize you, but they don’t say anything.”
He continues, “This brand is a lot of fun — they found me to be the guy to be in here and screw with people and just have fun.”
Aside from his Diet Pepsi partnership, Duhamel has been busy with his acting and will soon wrap work on his upcoming film Strings, which he spent a week filming in Canada.
“I really don’t want to be away from her right now. I definitely don’t want to be gone when the baby’s here,” he says. “But I feel very, very blessed to have a wife that’s going through this pregnancy so beautifully.”
As the future father gears up for daddy duty, he’s happily embraced the sweeter side of pregnancy — the cravings! — as Fergie attempts to maintain a balanced diet. “She’s really been good. I think that’s why she feels so good. She’s been eating really healthy,” he shares.
“She does [give into cravings] a little bit of course — she always has and she always will — but she stayed very disciplined because it’s all about what goes into her body goes into the baby.”
Duhamel is doing his part to stay physically fit, but the actor jokes that he’s given up on trying to achieve a brawny build. “I’m sort of in shape. I do exercise. I do work out, but I’m not like The Rock,” he says. “I try to stay healthy, I try to stay athletic and flexible, but I gave up trying to get big muscles years ago because it just didn’t happen.”
The proud parents-to-be just revealed that they’re having a boy, but they’re maintaining a code of silence when it comes to their name choice. According to Duhamel, even Fergie’s extended family do not know the moniker — and will not until baby’s big arrival.
“Some people may not like it, some people may think it’s really cool, but we don’t really care — that’s why we’re not telling anybody,” he explains. “We’re not even telling [Fergie's] mom because we don’t want to hear anything about it. That way you don’t feel like you’re second-guessing yourself. It’s between us — it’s a sacred thing.”
One thing’s for sure: the little one’s name plays to both Duhamel and Fergie’s senses of style.
“[The name is] kind of traditional, kind of not. My wife is a little rock and roll, so she’s a little bit more daring in that department than I am,” he says. “We decided on a name that we both really love and I think will suit this child.”
