Kylie Jenner packed pricey Knicks-colored lingerie for Indianapolis trip with Timothée Chalamet

Kylie Jenner has become a Knicks fan down to her knickers.

The makeup mogul has supported the New York basketball team at three of their most recent playoff games, sitting courtside with boyfriend Timothée Chalamet in outfits honoring the team.

While Chalamet is a die-hard fan, having grown up in Manhattan, he appears to have convinced his girlfriend to leave the Los Angeles Lakers behind in increasingly spirited ways — and she packed a surprise for her beau on their latest outing.

Jenner, 27, showed off the insides of her luggage after traveling to Indianapolis for Game 6 of the Eastern Conference Finals against the Pacers on Saturday, revealing a sultry underwear set.

Among the goods were a yet-to-be-released bra and panty set from Fleur de Mal, fashioned in blue silk with orange lace in honor of the NBA team.

The top ($128) and bottom ($68) are currently available for pre-order and estimated to ship on June 23 — but of course the reality star got her hands on silky pieces in advance.

Jenner may not have ended up stripping down to her skivvies, however, as the Knicks ultimately lost the game, costing them the series.

The “Kardashians” star hinted at her sports-dependent sex life with the “Dune” star ahead of the game, cheekily re-posting a “Sex and the City” clip in which Samantha Jones (Kim Cattrall) laments that she doesn’t “get laid unless the Knicks win.”

Indeed the couple have been enthusiastic game attendees, with Jenner wearing a nylon Knicks jacket over a white tank top with dark jeans for her most recent appearance. She accessorized with an electric blue Hermès Kelly bag, white Chanel pumps and her diamond-covered Cartier Panthère watch.

Also in her suitcase? A plethora of hats, a friendship bracelet, orange heels and two Knicks T-shirts, including one with “Looney Tunes” character Tasmanian Devil.

For his part, Chalamet went with one of his most daring orange-and-blue courtside looks yet, sporting a custom all-leather Nahmias zip-up jacket and matching groovy pants. He added his trusty Knicks-colored custom Chrome Hearts x Timberland boots and a Chrome Hearts belt as well as white sunglasses and a $11,400 Cartier necklace.

While he’s been ostentatious with his outfits — twinning with Jenner in orange leather jackets and all-black looks previously— we’re not sure if the commitment has extended down to his boxers.
