Kendall Jenner and Devin Booker shared a rare PDA at the Kravis wedding

At Kourtney Kardashian's wedding to Travis Barker, Kendall Jenner's dress was as bodycon as a Dolce & Gabbana column gown could be.  

She even posted a video of Kendall struggling to climb stairs in it.) 

But what made Kendall truly remarkable was who she spent the wedding with-and how openly she flaunted their relationship. 

She invited her boyfriend of over a year, NBA player Devin Booker, to the ceremony.  

The photographer snapped them as they walked into the ceremony holding hands. It was an unusual display of PDA for the couple.

Kendall has kept her romantic relationships the most private out of all the Kardashian-Jenner sisters.  

Harper's Bazaar reported in 2017 that she wouldn't talk about a partner unless they were very serious. 

At the time, she said that she wouldn't marry anyone. "I don't have any plans.". My life isn't long-term or serious like that.
