Is Khloe Kardashian engaged to Tristan Thompson? Fans think the on-and-off pair could be walking down the aisle soon, but insiders say there won't be any wedding bells soon for the stars.

Kardashian celebrated her 36th birthday on Saturday with a pink-themed party. She shared snaps of her svelte figure as she celebrated her big day on Instagram and eagle-eyed fans were quick to spot a huge diamond ring on that finger. Rumors started to fly that Thompson had finally dropped to one knee and popped the question.

While the two have been spending time together during the coronavirus lockdown and are reportedly on very good terms, a source said Kardashian is “taking it very slow.”

"Khloe seems very happy with where things are right now. He seems committed and has made changes," an insider told E! News. "Obviously Khloe is hesitant and is taking it very slow. The time they have had together during quarantine has been very special and meaningful."

Despite spending time together as a family with their daughter True, nothing has been confirmed about their current relationship status.

Another source, however, told Us Magazine the NBA star has been working on proving himself. He’s “stepping up” and is “fighting” to make their relationship work.

Thompson also posted a birthday greeting for his ex-girlfriend on Instagram. The athlete noted how Kardashian made him “an incredible person.

“I appreciate how I am able to learn from and grow because of you. I thank God for the beautiful and loving woman you are to everyone, especially our daughter True. You deserve the world Koko,” he wrote.

It can be recalled that in February 2019, Thompson allegedly cheated on the “Keeping Up With The Kardashians” star with Kylie Jenner’s best friend, Jordyn Woods. He and Kardashian have since been spotted together on a few occasions, but have not confirmed they’re back together.

The insider noted that Kardashian knows things may still change when the athlete returns to playing ball and being on the road often. “She isn't getting ahead of herself and she is just enjoying having him,” the source added.
