Hayden Panettiere poses with baby Kaya in new photo

NASHVILLE, Jan. 5 (UPI) -- Wladimir Klitschko took to Instagram on Sunday to share a new photo of fiancée Hayden Panettiere and daughter Kaya Evdokia.

The 38-year-old Ukrainian boxer posted a picture of the 25-year-old actress with the newborn. Klitschko and Panettiere welcomed Kaya on Dec. 9, and released a family portrait two weeks later to People magazine.

"#family #klitschko #newyear," he wrote. He recently captioned another snapshot, "A review on the year: The birth of my daughter, two successful championship defenses and many other achievements on the way. It was a great year and I'm looking forward to 2015."

Klitschko and Panettiere started dating in 2009, but broke up in 2011. The pair resumed their relationship after the actress split from NFL player Scott McKnight in December 2012, and announced their engagement in October 2013.

Panettiere came to fame on soap operas One Life to Live and Guiding Light in the 1990s, and subsequently portrayed Claire Bennet on NBC series Heroes. She currently stars as Juliette Barnes on ABC musical drama Nashville.
