Hayden Panettiere Cheers On Wladimir Klitschko's Brother

Hayden Panettiere leaves a McFit VIP party on Saturday (March 19) before watching Vitali Klitschko take on Cuban boxer Odlanier Solis in Cologne, Germany.

The 21-year-old Scream 4 actress pulled off a Burberry trench coat to reveal a sexy white dress by Roberto Cavalli at the event, where Vitali easily beat his opponent.

Also joining Hayden at the party and pictured is Natalia Klitschko, Vitali‘s wife!

FYI: Vitali is the brother of Wladimir Klitschko, Hayden‘s boyfriend.
