Wladimir Klitschko's fiancee Hayden Panettiere 'pregnant'

Wladimir Klitschko's actress fiancee Hayden Panettiere is reportedly pregnant with the couple's first child.

The Ukrainian boxer is believed to have been engaged to the 24-year-old American star for around a year following an on-off romance.

The couple first began dating in 2009, but later split in 2011 before rekindling their relationship.

According to Us Weekly, Panettiere, who has previously revealed a desire to raise a family, is pregnant with her first baby.

The pair were forced to postpone their wedding due to the civil unrest in Ukraine earlier this year.
