Hayden Panettiere and her fiancé Wladimir Klitschko are said to be expecting a child together. The Nashville actress and the Ukrainian boxer got engaged last year after an on-off three year relationship but were forced to postpone their wedding due to the ongoing civil unrest in 36 year-old Wladimir's home country.

"Hayden is totally pregnant!" an insider told Us Weekly, breaking the news which has not yet been confirmed by either party. Hayden expecting a baby wouldn't have come completely out of the blue either: the 24 year-old actress has previously explained how she feel like she was "born to be a mother" and has joked that hers and Wladimir's children would be "normal height" due to their extreme differences in height.

Whilst Panettiere, who made her name starring in action series Heroes, is the more famous of the two, Klitschko has had a pretty interesting life too. The heavyweight professional boxer is the longest-reigning and most accomplished IBF, WBO & IBO heavyweight champion in history.

He is the younger brother to the former WBC, WBO & Ring magazine heavyweight boxing champion Vitali Klitschko, who has also just been elected as the mayor of Kiev having been a key figure during the recent political protests.

With a PhD in sports science to his name, Wladimir is also fluent in four languages, including Russian and English. Therefore it will be interesting to see whether he and Hayden decide to raise their child to be bilingual, as Ashton Kutcher and Mila Kunis are planning with their own soon-to-be-born child.

Known as The Steel Hammer, then Dr. Steel Hammer, Wladimir has a formidable reputation in the ring and stands at a mighty 6 foot 6 inches, compared to his fiancée's teeny five foot. Despite his imposing height and list of sports accomplishments, he is also noted for his humanitarian work - having spearheaded several Sport For Good projects - and chess prowess so by all accounts he'll make a great father.

Hayden and Wladimir have not yet commented publically on the reports.
