Amanda Peet doesn’t understand why Diane Keaton doesn’t do more nude scenes.

The 69-year-old actress notably bared all in the 2003 film “Something’s Gotta Give,” starring both Peet and Jack Nicholson.

In a conversation with HuffPost Live on Thursday, Peet, who stars in HBO’s new series “Togetherness,” admitted that while the nude scene had to be “difficult” for the then-57-year-old star, she thinks Keaton “has a great body.”

“If I were Diane Keaton, I’d take my clothes off all the time!” Peet said.

Speaking about her time playing an on-screen love interest for Jack Nicholson, whom Peet also had to disrobe in front of — albeit only a bikini — the 43-year-old confessed to having been “terrified.”

Nicholson was daunting, “not in a ‘Shining’ way,” she explained, “but in a just, ‘You’re an icon and you’re standing right here and I’m looking up at you [kind of way].’ It’s that thing where there was a whole scroll going on in my brain the entire time: ‘Holy shit, holy shit, holy shit. Don’t fuck up, don’t fuck up, don’t fuck up.'”
