John Mulaney had a special visitor on the set of Saturday Night Live this weekend!

Not only did his girlfriend Olivia Munn stop by the show, but she also brought their adorable son Malcolm.
Of course, Olivia had to share some sweet snaps from their trip to the Big Apple, including a photo in matching black puffer coats.
And while Olivia has shared a lot of photos of the infant since the couple welcomed him in November, she says her snaps from the SNL set have become her "favorite."

"Malcolm visited SNL Thursday afternoon. Here he is looking like your uncle being carried out of a wedding because he went too hard," Olivia jokingly captioned the photo.
Honestly, her caption is spot on.
