Dominatrix date night! In their first joint sighting since news broke of Blac Chyna and Rob Kardashian's romance, Kylie Jenner donned head-to-toe leather for a meet-up with her beau, Tyga, at 1 Oak in L.A. on Thursday, January 28.

The Keeping Up With the Kardashians star, 18, wore a cinched leather top, leather J Brand leggings, a crossbody chain purse and pointed-toe pumps for her night out.

Though Jenner arrived with a friend, she left with her on-again, off-again boyfriend, who kept casual in a blue jacket, a plaid shirt, baggy jeans and a baseball cap.

As Us reported earlier this week, things have been tense in the Kardashian-Jenner family as of late, after Kylie's half-brother, Rob Kardashian, began dating Blac Chyna, Tyga's ex-girlfriend and one of Kim Kardashian's former best friends.

"There's a romantic vibe [between Rob and Blac Chyna],” an insider confirmed to Us Weekly.

And as a result, another source added, "The family is in a bind trying to be supportive of Rob's life while being sensitive of Kylie's relationship with Tyga."

Nevertheless, while the family may be on edge, there's one person who's taking the news in stride: Tyga. When E! approached the "Stimulated" rapper about the relationship on Thursday, he coolly replied, "Everyone deserves to be happy."
