Celebrity Couples With Huge Height Differences.

#10 Wladimir Klitschko (6'6") & Hayden Panettiere (5'1").

Seeing pictures of Hayden Panettiere and her fiancÃ© Wladimir Klitschko, you could guess that the actress and the Russian prize-fighter partner are of two different species. He looks tall enough to be two Haydens stacked on top of one another.

#9 Fergie (5'2") & Josh Duhamel (6'3.5").

This couple met after the Black Eyed Peas had an appearance on Duhamel's show "Las Vegas," and they married three years later. The two haven't let their 13-inch height difference come between them, and are still happily married.

#8 Nicole Kidman (5'10.5") & Keith Urban (5'7").

While Urban is only about an inch shorter than Kidman. They're happy together, however, and it's safe to assume that one of the reasons is their ability to talk Australian to each other.

#7 Sacha Baron Cohen (6'3") & Isla Fisher (5'3").

Although these two celebs were engaged for six years, they didn't marry until Fisher converted to Judaism for Cohen. Now they live happily with their three children, the youngest of whom was born in March of 2015.

#6 Ryan Sweeting (6'5") & Kaley Cuoco (5'6").

Married for only about a year and a half, this couple makes up for their short-lived nature by featuring a height difference of 10 inches!

#5 Will Smith (6'2") & Jada Pinkett Smith (5'0").

While Will Smith cuts an impressive figure by himself, he seems even taller when towering 12 inches over his wife of 18 years.

#4 Clare Grant (5'7") & Seth Green (5'4").

It's not that she, standing 5-foot-7, is really tall, it's that he, a mere 5-foot-four, is a pretty short guy. Despite all that, Green and Grant are happily married.

#3 Dax Shepard (6'2") & Kristen Bell (5'1").

Shepard and Bell waited until the part of the Defense of Marriage Act that didn't recognize gay marriages was struck down to get married themselves, but they were never waiting for Bell's 5-foot-1-inch frame to catch up to Shepard's 6-foot-two-inches.

#2 Mila Kunis (5'4") & Ashton Kutcher (6'2").

Although they had worked together for years on That '70s Show, Kutcher and Kunis didn't start dating until after Kutcher divorced Demi Moore in 2012. Now with a child of their own, this height-varied couple is still going strong.
