Well, this famous baby’s going to be extremely tall, munchkin-level short, or exactly average.

His or her celebrity parents must be the most mismatched couple in Hollywood, height-wise. But in all other ways, kinda perfect.

Teeny-tiny 24-year-old actress Hayden Panettiere is reportedly pregnant with her first child, to her 6 foot 6 fiance, Ukrainian boxer 

Wladimir Klitschko.

The couple have been engaged for about a year, and we haven’t heard if they’re planning to get married before or after the arrival of their little one.

But we do know that Hayden’s been maternal for quite a while.

This is what she told 

Glamour

 last year about wanting kids:

Hayden and Wladimir met at a book launch in 2009, dated for two years, broke up in 2011, got back together in 2013, and have been engaged since then. Sounds pretty standard for a Hollywood romance… or a normal-person one for that matter.

Congratulations Hayden + Wladimir. We still don’t know how you kiss one another without the aid of a step-ladder but we’re delighted you worked out how to make a baby human.
