Pete Davidson let a fellow Knicks fan know to keep his hands to himself.

While the “King of Staten Island” star stopped to take photos with fans after the basketball game at Madison Square Garden, one man got a little too close, prompting Davidson to take action.

Video posted to social media of the interaction shows the unnamed man, who was dressed in a pink Polo and Knicks cap, putting his arm around Davidson as he was taking a selfie with a different fan.

The former “Saturday Night Live” star then shoved the man and exchanged words with him before resuming snapping pictures with other, less handsy people.

He even threw up a peace sign while posing with one woman after the aggressive interaction.

Davidson’s rep didn’t immediately return Page Six’s request for comment.

During the game, 29-year-old Davidson sat next to comedian Jon Stewart as the Knicks took a 3-1 series lead over the Cavaliers, winning 102-93 Sunday afternoon.

His girlfriend, Chase Sui Wonders, didn’t attend the exciting game.

The “Suicide Squad” actor and Wonders, 26, first sparked dating rumors in December following his brief romance with Emily Ratajkowski.

Despite only having dated a few months, the “Bodies Bodies Bodies” co-stars’ relationship appears to be very serious, as the pair couldn’t keep their hands off each other while vacationing in Hawaii.

Davidson also has put his luxe Brooklyn Heights pad up for rent for $28,000 per month, sparking rumors he and Wonders may want to find a place of their own.

Realtors representing Davidson’s pad are looking for a tenant to rent his place on a 12-month lease.

The “Meet Cute” actor, 29, had been leasing the space after moving from his native Staten Island in February 2022.
