Khloe Kardashian and her new beau, Cleveland Cavaliers player Tristan Thompson, are taking things to another level!

After going on a romantic vacay in Mexico last week (at the time, People reported that the duo were a “mini-thing"), now it looks like they're a BIG thing because someone just posted a video of Khloe kissing the hunky baller on Snapchat.

In the clip, which was posted on Friday night, one of Khloe’s friends sneaks a shot of the duo, who are dancing to Juvenile’s “Back That Ass Up." Keeping it classy! “[They] are seeing each other,” an insider told Us Weekly. Another source added that the starlet “seems more hopeful with Tristan — he’s different than the other guys she’s dated. He’s a committed, relationship guy.”

Khloe's pal Malika Haqq introduced the two in August, and the lovebirds were spotted hanging out a Beverly Hills mansion earlier this month, and prior to that they were spotted partying at Bootsy Bellows in West Hollywood. Later this week they were spotted all over each other at the Drake concert! “They like each other and are hanging out," a source for the mag added. Good for her!
