John Mulaney cant get enough of his tiny man.

The Comeback Kid comedian celebrated his son Malcolms 2-month birthday on Tuesday with a carousel of sweet photos on Instagram.

Happy Birthday to the tiny man who has been stuck to me for two months, he wrote on Instagram. Whoever you are sir, you sure are a fun companion.

Mulaney and actor Olivia Munn welcomed their son, Malcolm Hip Mulaney, in November.

Munn was in one of the photos Mulaney posted for Malcolms birthday, which showed the couple embracing with their backs towards the camera.
