See 'uncle' Pete Davidson meet John Mulaney and Oliva Munn's adorable son

Saturday Night Live comedian John Mulaney introduced his son Malcolm to "uncle Pete," aka co-work and pal, comedian Pete Davidson, who recently went on a steamy vacation with Kim Kardashian.

Pete hung out with John Mulaney on Friday and met his new baby, Malcolm, as seen in an adorable video that John shared to his Instagram Story on Jan. 28.

The footage shows "Uncle Pete" meeting John's 2-month-old son, who he shares with actress Olivia Munn. Dressed in a grey hoodie and blue pants, Pete was pictured cradling Malcolm on the couch, clutching the newborn's little fingers and squealing, "Aww!"

"Yeah, babies are all head," Pete said to laughs from others in the room. The Big Time Adolescence actor then smiled to reveal an apparent chipped tooth, adding, "They're, like, all head."

Their sweet moment was set to the tune of "F.U.N. Song" from SpongeBob SquarePants, with the lyrics, "F is for friends who do stuff together/ U is for you and me/ N is for anywhere and anytime at all/ Down here in the deep blue sea!"
