Khloe Kardashian, Tristan Thompson get close at Halloween party

LOS ANGELES, Oct. 31 (UPI) -- Rumored couple Khloe Kardashian and Tristan Thompson got hot and heavy at a Halloween party Sunday.

The 32-year-old reality star and 25-year-old NBA player, who dressed as Marvel characters Storm and Black Panther, were spotted dancing and kissing at the Cleveland Cavaliers costume bash.

Kardashian shared several posts from the party, including a photo of herself gazing up at Thompson. She also posted Snapchat videos of herself grinding on and making out with the Cavaliers power forward.

The Keeping Up with the Kardashians star and Thompson were first linked in September after a getaway to Mexico. The pair have reportedly gotten more serious since Kardashian reached a settlement in her divorce from Lamar Odom.

"Khloe has been spending a lot of time in Cleveland with Tristan," a source told People last week. "She's very supportive of him, and they are getting serious. They really dig each other a lot, and she's planning to spend more and more time out there with him."

"Khloe and Tristan are doing really well. They are exclusive," an insider previously told E! News. "There is a lot of chemistry between the two of them and they are happy together."

Kardashian had filed for divorce from Odom again in May after putting proceedings on hold due to the former NBA player's hospitalization. The pair initially split in 2013 after four years of marriage and are expected to finalize their divorce in December.

Kardashian and her family recently returned for part two of Keeping Up with the Kardashians Season 12. The E! series airs Sundays at 9 p.m. ET, and resumed production last week following Kim Kardashian's robbery in Paris.
