Find out what Ashton Kutcher wanted to name his baby boy (before Mila Kunis 'knocked down' the idea)

Ashton Kutcher and Mila Kunis are preparing to welcome their second child, but the couple isn't ready to share any possible names for their forthcoming son.

Kutcher sat down with Conan O'Brien on Wednesday, where he opened up on one name he'd been arguing for, but to no avail: Hawkeye!

"I'm an Iowan, so to have a kid named Hawkeye?" marveled Kutcher. "And it's like M.A.S.H.! Like, he could be a doctor!"

Kutcher was of course referring to the character Benjamin "Hawkeye" Pierce, a Korean War field surgeon in the beloved film and TV franchise M.A.S.H., played by Donald Sutherland in the 1970 movie and Alan Alda in the long-running CBS series.

Unfortunately for Kutcher, the name "didn't fly" with his pregnant wife.

"It didn't cross the Mila threshold," he joked. "It came to the threshold, but got knocked down."

The couple welcomed their daughter, Wyatt Isabelle, in October 2014. While Wyatt was considered by some to be a unique name, Kutcher wouldn't elaborate on any names the couple are considering since Kunis put the kibosh on Hawkeye. However, he admitted that they do "have a name dialed in."

"We've had [the name] for a while," Kutcher said. "But the problem is, if you get the name too soon, suddenly there's like, slight trepidation about the name."

On Tuesday, the expectant mom was spotted walking around L.A. rocking a pair of boyfriend jeans, sneakers, and a cute striped tee that showed off her sizable baby bump.
