Kendall Jenner and Hailey Bieber Keep It Casual on the Courtside at Los Angeles Lakers Game Bieber, meanwhile, is back to being all glammed up after keeping things casual the past few months — first getting cheeky in bikinis during a beach vacation with husband Justin Bieber and friend Kendall Jenner. Back home, she and her husband got bundled up for a Maple Leafs hockey match, with the former wearing a blue roll-neck sweater in the team’s colors. She also reunited with Jenner for a sporty night out at a Los Angeles Lakers basketball game, donning a backward jean cap, a leather jacket and blue jeans. (L-R) Justin Bieber, Hailey Bieber.
