She added regarding the birth of Ashton's sister Tausha's son in September, "My sister-in-law had a little boy two weeks prior to us having our little girl and it is completely different. Everything."
"Sister-in-law"?! Did Mila secretly marry Ashton?!
The former That 70s Show star already seemed to have dropped her baby weight as she stepped out wearing a sexy, short black dress (LBD). She credited her weight loss to breastfeeding.
Mila -- who called the Late Late Show her "favorite show in the world to do" -- and Craig both have Scottish roots, and when asked if she plans to raise her baby Scottish, the actress responded "absolutely." In fact, she even bought Ashton, 36, a kilt.
"It turned out great, because you know, nothing’s under the kilt," she said. "He loves kilts. The day that I landed, when we got back from Scotland, was on St. Patty’s Day. And then we went out to a bar and he wore his kilt and now every St. Patrick's Day."
