Why Are Kate Beckinsale And Ex Recreating Their Daughter's Birth?

It sure can spice up a late-night chat.

Always a baby to me #Lily -- See more tonight on the @latelateshow ✨

"Underworld" star Kate Beckinsale and ex Michael Sheen of "Masters of Sex" appear to remain good friends -- and how.

The actors hilariously recreated a 1999 hospital photo they took just after the birth of their daughter Lily and posted it on Instagram Tuesday next to the original.

Beckinsale explained in the caption that we could see more on "The Late Late Show" with James Corden.

And now we have. On Tuesday night's show she showed the host an even goofier photo of the three recreating the actual birth, with Sheen holding the mother's leg up for easier delivery as Lily (at age 16) bursts into the world.

"He did hold a leg," Becksinsale told Corden of the real original delivery. "That was his job."

Beckinsale, 42, and Sheen, 47, split in 2003 but we're glad to see they're on such good terms. We can't wait for the next family moment redux.

Here's the clip:
