Kylie Jenner‘s embracing her role as the New York Knicks’ good luck charm … heading all the way to Indianapolis in hopes of keeping her boyfriend Timothée Chalamet‘s favorite team’s championship dream alive.

The actor and the mogul sat courtside together Saturday night … both decked out in Knicks blue and orange at the biggest game of the year.

Check out the clip … Kylie’s so excited to be there with her man — wrapping her arms around him and trying to get him hyped while he throws up a peace sign for the camera.

While Kylie and Timothée have been mainstays at Knicks games during the postseason, it may shock some that they’re attending Game 6 … ’cause it’s not a short jaunt to Madison Square Garden.

The supercouple’s in Indianapolis for this … and, ya gotta think Chalamet was begging Jenner to come to this one — since his team’s 2-0 with her in attendance this postseason.

It certainly seems Kylie’s becoming a big b-ball fan … or, maybe she just likes gettin’ it on when they win!
