IF THE SHOE FITS
Their height difference: About 4 stilettos
After announcing their engagement in October, Hayden Panettiere and on-again beau Wladimir Klitschko are taking their relationship to new heights with the Dec. 9 birth of their first child, daughter Kaya Evdokia. So what stands between the 25-year-old actress and her 38-year-old fiancé other than their 13-year, four-month age gap? Their 1-foot-4.5-inch (that's 16.5 inches!) height difference. Real talk: Panettiere's going to need more than a 4-inch pair of heels – try four pairs – like the ones she rocked at the 2011 Tribeca Film Festival, to see eye to eye with her man.

And when it comes to heating it up, um, horizontally, the actress told Ellen DeGeneres that year, "Yeah, it works. We find a way. Where there's a will, there's a way!" Mahalo for that TMI, Hayden!

IN THE BAG
The difference: About 2½ clutches
Well, that's one way to make a big statement on the red carpet. Stepping out at May's Sports Emmy Awards, height's clearly just a number for the couple, who equally stun at the reception.

JEAN-IUS OF LOVE
Their height difference: About 2 pairs of short-shorts
So what can we learn from the new parents's romance? In fashion as in life, it's not size but fit that matters most. So if the short-shorts fit...
