Ryan Reynolds is officially one of the cutest celebrity dads ever!

The 38-year-old Deadpool star is seen carrying his and wife Blake Lively's first child, baby daughter James, in a front carrier in a new pic the 27-year-old actress posted on Instagram on Sunday, Father's Day.

"Happy Father's Day!!!" Lively wrote, alongside the pic, which shows the little girls itty bitty polka dot sock-clad feet poking out from the bottom.

"@vancityreynolds Since the day our baby was born, I've felt so strongly in my heart that you were most likely the father," she added. "#ILoveYouSoMuchItsSilly."

"On Father's Day, my daughter smiled at me," Reynolds tweeted. "It was all the gift I needed as I packed a bag and left for 6 years to write a book on parenting."
