Hayden Panettiere's beautiful baby girl is only a month old, but we've already fallen in love with her! The 'Nashville' actress and her fiancé Wladimir Klitschko welcomed Kaya Evdokia Klitschko on Dec. 9, and she is simply too cute for words.

Unsurprisingly, Klitschko -- a Ukrainian heavyweight professional boxer -- already seems to be wrapped around his little girl's finger, and he has the Instagram photos to prove it! Pictures show the new parents posing and smiling with their baby girl, with Panettiere absolutely glowing. And is it possible Kaya is already perfecting her smile?!

Despite what seem to be planned portraits, Panettiere went light on the makeup, but she still looks flawless. Motherhood looks good on Juliette Barnes ... err, we mean Panettiere. There are also a few candid photos on the Instagram account, showing the couple in real-life situations with their baby girl. No matter if it's posed or candid, the photos are aww-worthy!

Kaya is the couple's first child. News of their engagement broke in 2013 following a brief split in 2011, after a couple of years of being together. Juliette Barnes fans can stop stalking Klitschko's Instagram account when 'Nashville' resumes on Feb. 4.
