Malcolm Mulaney just gets cuter and cuter - we see it, and we know his parents see it, because they are clearly OBSESSED with him. (I mean like, if you've seen those cheeks, you'll understand.)

Yesterday, Malcolm Mulaney - the new baby of comedian John Mulaney and actress Olivia Munn - turned four months old, and both of his parents posted on Instagram to celebrate the small milestone.

Mulaney posted one picture - a throwback of himself in the hospital with his son the day he was born, looking over at him with that new-dad wonder:

Munn, meanwhile, posted a sweet photo of the two of them together on the bed - with a bit of biographical information about the little guy, who apparently LOVES books and bathtime.

And, of course, Mom couldn't resist posting some more cute shots of her baby boy on his miniature birthday - she later posted a few shots on her story as well

  But BY FAR the sweetest is this video of John Mulaney telling his son he loves him - and saying goodbye before he has to hop on a plane to Texas.

Mulaney is jetting off to begin another leg of his From Scratch tour - a very long one, at that. The stand-up comic will be on the road for much of the Spring and Summer with his new routine, which he has been workshopping since late 2020.

We wish him the best of luck on his performances - and wish Malcolm a very happy four month birthday!
