It looks like Bobby Cannavale and Rose Byrne have a country music fan on their hands. The actor took to Instagram today to share a rare photo of the couple's 2-month-old son Rocco, and he's too cute for words.

In the snap, Rocco is wearing a hilarious onesie featuring a drawing of famed singer Dolly Parton's as he is fed a bottle by his famous dad. "Well, Hellooooo Dolly! @deerdana Sorry. Feeling show tuney today," Cannavale funnily captioned the picture, referencing the iconic Broadway musical Hello, Dolly!.

But this isn't the first time the proud father has posted photos of his little guy. Last month, Cannavale shared 'grams from their family getaway to Florida, giving us our first glimpse at the newborn.
