Bob Saget, Macaulay Culkin, and Seth Green are giving us some serious '90s nostalgia.
Saget Instagrammed a selfie of the three stars hanging out in Times Square in New York City on Thursday, along with Green's wife, actress Clare Grant.
"Fun times last night after show in the #TimesSquare with friends @ClareGrant, Macaulay Culkin, and the master of the selfie, my pal @SethGreen," Saget wrote.

Check out a long-haired Culkin, 35, hilariously posing for the rare snap.
Culkin presumably met Saget, 59, through 41-year-old Green, a longtime friend of the notoriously private former child star. Saget and Culkin both starred in Green's animated Adult Swim television series, Robot Chicken.
Saget also posed this cute selfie with Culkin and Green backstage at his Broadway show Hand to God, in which the Can't Hardly Wait actor gives him a giant bear hug.
"So fun my friend @SethGreen, his beautiful wife @ClareGrant, and Macaulay Culkin came to @HandToGodBway last night," the Full House star wrote.
WATCH: Here's What the Cast of 'Home Alone' Looks Like 25 Years Later
Culkin running around New York City during the holidays is obviously giving us some much welcome Home Alone flashbacks. In October, ET exclusively caught up with a few of the stars from the 1990 classic to celebrate the beloved film's 25th anniversary. Director Chris Columbus recalled shooting the film's most iconic moment -- a then 9-year-old Culkin's signature scream.
"The script called for [Macaulay Culkin] to put shaving lotion on and suddenly it burns his skin and he screams," Columbus said. "We didn't know it was going to be the universal image for Home Alone."
