Ken Jeong donned his birthday suit in The Hangover and he does it again in The Hangover Part II. But before he displayed his body, he asked for approval from one person – his wife.

“I got her permission. I’m not stupid,” the actor, who plays flamboyant, foul-mouthed gangster Leslie Chow, told PEOPLE at the film’s Los Angeles premiere this week. “I ran it by her before I ran it by [director] Todd Phillips.”

And obviously his wife, Tran, gave her hubby the green light. “I’m very blessed to have a supportive wife,” said Jeong. “In fact, she said this will be a feel-good movie because every guy will go home feeling good about themselves.”

Jeong, who at the 2010 MTV Movie Awards paid a tearful tribute to his wife and her successful fight with breast cancer, is happy to report her clean bill of health.

“She’s been breast cancer free for the passed three years,” Jeong said. “We have two girls, Alexa and Zooey, and they will be 4 years old next Thursday, the day Hangover 2 comes out, so we’re really blessed. I’m just so glad everyone is happy and healthy. That’s all you want in life.”

Jeong is also grateful for his other “family” – his castmates in the movie. “[The Hangover Part II] is like being reunited with family again,” said Jeong.

And he has nothing but praise for his costars, particularly Bradley Cooper. “He’s one of my best friends and he’s a movie star now and he’s the same guy,” says Jeong, “unaffected and just a decent person. I love him.”
