Hayden Panettiere at Oktoberfest in Munich

With a giant jug of beer in hand, Hayden Panettiere looks the part as she dressed up in full traditional German dress for Oktoberfest celebrations.

The actress, who turned 21 last month, poured her figure into a racy low cut dirndl at the party in Munich, Germany, and was joined by her boyfriend, Ukrainian boxing champion Wladimir Klitschko.

The Heroes star was enjoying the festivities last night at Boris and Lilly Becker's Oktoberfest Trophy 2010 bash. Check out 7 more images after the jump.
