Actor Timothée Chalamet declared “Knicks in 5” after his hometown team pulled off a historic comeback to beat the Spurs 107-106 in Game 4 of the NBA Finals on Wednesday night.

“Come on, it’s the Knicks, baby!” Chalamet yelled while on the court at Madison Square Garden, as seen in a video online after the Knicks took a 3-1 series lead.

He held up five fingers before bringing his hands to a prayer gesture.

He turned around and continued celebrating as his girlfriend Kylie Jenner and Jordyn Woods, fiancée of Knicks center Karl-Anthony Towns, were talking nearby.

Chalamet wasn’t feeling as joyous before his on-court celebration when the Knicks were down by as many as 29 in the third quarter.

The Knicks rallied back in the second half and sealed the win when forward OG Anunoby’s tipped in a rebound of a long 3-pointer by star guard Jalen Brunson with 1.2 seconds remaining to give the Knicks the lead.

Game 5 is Saturday night in San Antonio, with the Knicks a win away from their first NBA championship in 53 years.
