Heigel and her husband, musician Josh Kelley, welcomed baby Joshua on Dec. 20 -- and have shared tons of adorable pics of the newborn since.
In fact, Kelley celebrated his 37th birthday last week with tons of baby "snuggles."
"How @joshbkelley is finishing off his birthday, with sleepy snuggles from his namesake! Could not be more grateful for this extraordinary man and for this extraordinary day that he was born!" Heigl sweetly captioned a sleepy snap of the two.
