Keeping up with the Kardashian and Jenner girls' love lives and boyfriends is a full-time job these days.

Just when you thought one sister had broken up with her boyfriend, another sibling starts hanging out with him. It's so confusing. The most recent sister-ex run-in includes Kylie Jenner.

Kylie was spotted on Sunday night with Khloe Kardashian's ex, French Montana, in Hollywood, California. She was seen leaving The Nice Guy restaurant with Khloe's former bae, before the two hopped into Kylie's red Porsche.

Khloe and French were linked in 2014 (and broke up in December 2014), and have kept things cordial since their split. In fact, French just appeared in an episode of the family's reality series, where he awkwardly ran into Khloe at the home of Kourtney Kardashian's ex-boyfriend, Scott Disick.

Although it looked a little strange when the former couple saw one another, it's definitely not uncommon for the close-knit family to see each other's former flames.

Despite no longer dating Kylie's sister, French looked happy while spending time with the cosmetic guru over the weekend.

The Keeping Up With the Kardashians star let French drive her car as they took Snapchat videos together. The rapper even bought Kylie a bouquet of red roses from a lady selling them on the side of the road.

"Aw, French. Stop! Stop!" Kylie said in the video when he decided to surprise her with the flowers.

French isn't the only guy the 18-year-old has hanging out with since her split from Tyga in May.

While she is not romantically involved with Khloe's ex, she has been linked to up-and-coming rapper PartyNextDoor.

"Kylie is just living her life right now and having fun," a source told ET about Kylie's relationship with the rapper.

Meanwhile, Kylie has also found the time to post even more sexy photos than usual, including a few where she shows off her, um, assets.

"Ernie," Jenner captioned an Instagram photo where she shared more than her new puppy. The young star strategically revealed a cute angle of her dog, while serving up some serious skin in her cut-off jeans.

When Kylie isn't posting sexy pics in her bikini or of her behind poking through her jeans, she's proving that being makeup-free can be a great thing.
