Last night was a HUGE one for Gigi Hadid: The 21-year-old-model not only strutted her stuff at her very first NYFW show, the show she walked in was actually the launch of a capsule collection she helped design: Tommy Hilfiger鈥檚 Tommy x Gigi.

Naturally, Gigi received major congrats from many of her closest pals, such as Taylor Swift and Martha Hunt (who were front-row singing along to Calvin Harris), her boyfriend Zayn Malik and her family.

One person noticeably absent from the loving (and public!) well wishes of Gigi鈥檚 nearest and dearest, however? BFF Kendall Jenner.

A model herself, Kendall had other engagements to attend to on Gigi鈥檚 big night: The Vogue September cover girl was instead on hand for Harper鈥檚 Bazaar Celebrates ICONS by Carine Roitfeld event, so her absence from the show was surely excusable.

Yet, contrary to the duo鈥檚 Victoria鈥檚 Secret catwalk days of yore, which saw both girls posting plenty of kudos and shared hugs, Kendall posted not so much as a 鈥渃ongrats鈥漷o Gigi last night, leaving us to wonder: the hell鈥檚 up with that?

A post shared by Kendall (@kendalljenner) on

She certainly wasn鈥檛 too busy to post the above shot of herself and fellow model Hailey Baldwin (who also walked the Tommy runway) post-show, a fact that had us SERIOUSLY scratching our heads. In fact, come to think of it, we haven鈥檛 actually seen Kendall and Gig together in quite some time 鈥 since the MTV Movie Awards back in April!

While some may speculate that the rift has to do with Gigi鈥檚 new next-level closeness to Taylor Swift (who, you might recall, has been steady feuding with Kendall鈥檚 sister Kim and brother-in-law Kanye West for some time now) OK! reported back in April that tensions have actually been mounting due to the ladies鈥 men.

With Gigi back together with Zayn Malik and Kendall reportedly shacking up with Harry Styles (yes, the same Harry Styles that infamously spawned so many of Taylor Swift鈥檚 breakup hits), Kendall apparently had something to say about Zayn publically bashing his former 1D bandmate Harry, and Gigi wasn鈥檛 having it.

Yikes!

While it鈥檚 entirely possible that Kendall wished her former inseparable buddy congratulations in private, considering the fact that girl even documents being stuck in an elevator for 10 minutes, we鈥檙e thinking whatever rift went down over the guys is still ongoing.

Do you think Kendall鈥檚 lack of congrats was a major snub? Share over @BritandCo!
