Dwayne Johnson Singing Happy Birthday to His 6-Month-Old Will Mess With Your Hormones

It feels like just yesterday our hearts were exploding over Dwayne Johnson's first photo of his daughter Tiana Gia resting on his bare chest after her birth, but that little peanut is already 6 months old. To celebrate his baby girl's first half birthday, Dwayne shared a video of himself singing "Happy Birthday" with adapted lyrics to Tiana — and holy hell, it is cute.

"Happy 6-month birthday to our lil' disrupter, Tiana Gia," the dad of three wrote on Instagram. "We're a family of non-traditionalists, so we celebrate everything."

Hear Dwayne's heart-melting rendition of the birthday song above, and see the photos of Tiana he's posted so far ahead.
