It's one thing to post a regular old throwback photo, but Kate Beckinsale and her ex Michael Sheen showed us how to take it to the next level on Tuesday, May 17, 2016. The former couple posted a recreated TBT pic of her daughter Lily Sheen's birth on Instagram, and the results were outright hysterical ... and pretty darn cute.

Kate posed with her now teenage daughter on her bosom while laying in a bed with Michael smiling behind them.

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

"Always a baby to me #Lily," she captioned the side by side photo.

And added, in a quick a plug for her appearance on "The Late Late Show" with James Corden: "See more tonight on the @latelateshow."

By more, she means more of the series of photos they took re-documenting Lily's post-birth experience back in 1999, in honor of her 16th birthday!

"I wasn't naked," she told E! News a while back. "I was actually in a very nice cigarette pant and a high heel. Michael took one of my legs [and held it up] and Lily came from behind and was diving between my legs."

What a unique family activity to say the least, right? Well, at least Lily can rest assured that her parents still get along after dating from 1995 to 2003 -- a whopping 8 years.

Kate recently split from Len Wiseman, who she married way back in 2004. But Michael is currently off the market, as he's been linked to comedian Sarah Silverman.

We'd love to see what other recreated pics this trio can come up with!
