"She has a real fetish for Indian men," 42-year-old Shepard laughs, to which his wife responds, "I do, they're so beautiful."
And like a good "wingman," Shepard approached Ahmed for Bell, which led to a hilarious encounter.
"I said to him, 'Hey, my wife has a crush on you. I'd love to introduce you to her,' thinking she'd be nervous to say that. But here was her first line when she walked up to him ..."
"Out of my mouth came, 'I find you very attractive,'" Bell recalls.
Not surprisingly, Ahmed appeared to be at a loss for words.
"[It] made him very nervous because he looked at me like, 'Is this their perverse setup? Like, is he gonna get jealous and fight for her, or, is this, like, an opportunity for a three way?' You can see him going back and forth."
"We put him in a very awkward position, but we both were being honest, and I just told him how fabulous I think he is and how easy he is on the eyes," Bell says.
For the record, Shepard totally agrees.
"Beautiful skin, just, beautiful skin," he cracks. "It's hard not to notice."
Later, the couple opened up about Shepard's new film, CHiPS -- based on the 1970s television series of the same name -- which the former Punk'd star also wrote and directed. Bell has a role in the film as his "trashy, estranged trophy ex-wife," and it turns out the Good Place actress went through a bit of pain to play the role. Bell says she thought her character should have fake boobs, so she stopped breastfeeding for a day in order to have bigger breasts.
"It was mildly painful but it was worth it," the mother of two says. "This was my version of Christian Bail losing 120 pounds."
"I was nervous there was going to be a medical issue by the time we shot her in her bathing suit," Shepard says.
ET spoke with the couple at the People's Choice Awards earlier this month, when they got candid about how their relationship has changed through the years.
"We've gotten a lot older and it's evident," Bell said. "We've changed a ton but for the better."
"Our relationship was turbulent when we started," she added. "But there was a very strong attraction that was obviously physical but also emotional, mental, intellectual, and we worked through a lot of our own problems to get to a really good marriage."
