Hayden Panettiere with her boyfriend join Oktoberfest party: 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.

The couple, who attended The United Peoples Charity Event the night before, enjoyed an evening of beer and bratwurst whilst dressed in their traditional German attire. Hayden was wearing a low-cut red, white and black dress with a trilby type hat with white feathers on it. Her other half wore a red checked shirt and green velvet waistcoat. Together, they indulged in huge glass tankards of beer and traditional German food.

The annual event, hosted by ex World Tennis Champion Boris Becker and his wife Lily, was held in the Hippodrom - one of the most famous tents at the Munich Oktoberfest which is often frequented by celebrities. The evening party followed a charity golf tournament which benefited the champs Clever-Becker Foundation. Participants in the tournament were then invited to join the Oktoberfest party in the tent.
