You know it’s a big game when Kylie Jenner is back in her place next to boyfriend Timothée Chalamet on celebrity row at Madison Square Garden.

Jenner sat alongside her Knicks superfan beau between fellow actor Ben Stiller and his wife Christine Taylor. SNL alums Tina Fay and Tracey Morgan were on the other side for Tuesday’s critical Game 5 against the Hawks in the team’s first-round series.

It was Jenner’s first appearance this postseason, as she was not with the “Marty Supreme” star at MSG for Game 2.

Stiller, 60, was in the middle of some controversy last week after an ill-timed X post.

He wrote “Got it done” after the Knicks beat the Hawks in Game 4. It was misinterpreted as a reaction to the shooting that took place at the White House Correspondents’ Dinner, which ended around the same time.

The Post also spotted “Vampire Dairies” star Paul Wesley and fiancée Natalie Kuckenburg walking into The World’s Most Famous Arena for Game 5.

Plenty of the usual Knicks alums were also in-house, including John Starks, Patrick Ewing, Stephon Marbury, Walt “Clyde” Frazier, Bernard King, Carmelo Anthony and Latrell Sprewell.

Giants running back Cam Skattebo was also in the house, along with singer Rauw Alejandro.

Spike Lee, as usual, was in his customary seat on the first row. 

The Knicks, who lead 64-48 at halftime, were looking to rally from 2-1 down to grab a 3-2 lead and push Atlanta to the brink.
