Hayden Panettiere was ringside to cheer on her boxer fiance Wladimir Klitschko as he retained his world championship title in a high-profile fight in New York City on Sunday night (26Apr15).

The Ukrainian sportsman took on Bryant Jennings in a bout at Madison Square Garden in Manhattan and the Nashville actress was seated in the front row showing her support with enthusiasm.

After Klitschko defeated Jennings, Panettiere was pictured waving a Ukrainian flag during her partner's victory celebrations, while other stars ringside for the match included Hollywood veteran Bruce Willis.

Klitschko and Panettiere welcomed their first child, a daughter named Kaya, in December (15).
