Wladimir Klitschko (6’6) and Hayden Panettiere (5’0) – 17 inches

Athlete Wladimir Klitschko’s height is so attention-grabbing that it was impossible for people not to notice this. In fact, “Bring It On” star Hayden Panettiere was so stunned by their 17-inch difference when they first met at a book launch, which was how their story started.

However, Panettiere wasn’t intimidated and was actually impressed by his height. Unfortunately, despite being each other’s rocks in tough times, they suffered an on-again, off-again relationship. Luckily, they remain close in the midst of the problems for the sake of their daughter Kaya.
