Kim Kardashian wasn't the only celebrity showing off her curves at Oktobertfest this year -- because this weekend, Hayden Panettiere followed suit.
Dressed in a low-cut German dirndl dress, Hayden celebrated alongside giant boyfriend Wladimir Klitschko at Boris Becker's bash at the Hippodrom on Saturday.
Hayden was photographed enjoying a beer at the event -- she just turned 21 last month.
