John Mulaney Takes A Father-Son Stroll With Baby Malcolm In L.A. After Receiving A Visit From 'Uncle' Pete Davidson: Photos

Proud new papa John Mulaney took his baby boy out for some fresh air over the weekend.

The stand-up comedian, 39, was seen taking his and girlfriend Olivia Munn's two-month-old son Malcolm out for a walk in Los Angeles on Sunday, February 6, while enjoying the sunshine-filled day.

Mulaney looked snug in his black pull-over sweatshirt that he paired with royal blue track pants and a L.A. Dodgers cap, as he carried his snuggled up little boy — who was born on November 24 — in a papoose on his chest.

The father-son outing comes after young Malcolm had a very famous visitor stop by: the former Saturday Night Live alum's close pal Pete Davidson!

As OK! previously reported, The King of Staten Island star, 28, paid a visit to the new family on Friday, January 28, and Mulaney documented the special moment on his Instagram account.

“Uncle Pete!” the funnyman wrote alongside a snap of a chipped toothed Davidson — who was rocking the questionable look for an upcoming film — smiling as he cradled the newborn. In a clip, Kim Kardashian's boyfriend can be heard saying, "Yeah, babies are all head. They're like all head," as he gazed at baby Malcolm.
