Hayden Panettiere's fiancé, Wladimir Klitschko, is riding high only days after welcoming baby girl Kaya with the Golden Globe-nominated actress.

The professional boxer took to Instagram to share his excitement. "A review on the year: The birth of my daughter, two successful championship defenses and many other achievements on the way," he captioned the below photo.

"It was a great year and I'm looking forward to 2015. I'm ready to take on new challenges!"

Hayden gave birth to the couple's first child on Dec. 9 and was eagerly anticipating her arrival just days before, telling Hello! magazine, "I'm so ready to hold my baby girl—I'm going to be a very hands on mom."

The 25-year-old added, "I'm thrilled that I am having a girl first because I feel like I know a lot about raising a strong woman. I feel very empowered myself and I think my daughter will, too."

As for Wladimir, the 'Nashville' star is confident he's going to be a great father. "He's such a resilient guy. He's so calm and patient," she adorably shared. "I have never even heard this man raise a voice."

OK, we may have a new favorite Hollywood couple. But if they really wanna be No. 1 on our list, they'll have to share a picture of baby Kaya (wink, wink).
