Khloe Kardashian has diamond rings BACK on her left wedding finger while climbing into a Ferrari... as Tristan Thompson reunion rumours persist

Khloe Kardashian was flashing a lot of Monday evening as she headed to sister Kylie Jenner's Nightmare On Elm Street makeup launch dinner at her lavish mansion.

The 37-year-old Revenge Body host's curves looked sensational in a skintight Chanel jumpsuit in black with white Cs.

But the mother-of-one was showing off something else too: the two diamond eternity wedding bands on her left wedding finger.

After the sister of Kim Kardashian split from Tristan Thompson earlier this year, she took off any diamond rings on her left hand.

When she was with the basketball star, she slipped on several large diamond engagement rings on that finger and often wore the same diamond eternity bands.

That left finger was bare for a long time after Khloe and Tristan went their separate ways.

She did not have any baubles on that finger during her latest Good American jeans campaign nor did she have bling on for her neon swimwear line launch. 

But on Monday they were back on and she made a point to show them off with a close up photo taken while sitting in the driver's seat of her black sports car.

And the workout fanatic also gave a good look at the rings when holding on to the front door of her snazzy Italian car.

The rings were massive with another smaller one on her pinky. She added long white nails with points that made typing look impossible.

The toned pinup, who used to say she was the 'fat' Kardashian in her youth, also was seen leaning on her car.

Her jumpsuit was unzipped just so, revealing cleavage.

The Good American designer also had on black pointy stiletto heels. And her dirty blonde hair was worn down in soft, blown-out waves. 

The images also seemed to have a filter on them that made her resemble her Bravo pal Kim Zolciak of Real Housewives of Atlanta and Don't Be Tardy fame.

In September it was reported that Thompson is 'still very flirty' with Kardashian.

The Keeping Up With the Kardashians star and the 30-year-old are doing a 'great job' co-parenting their three-year-old daughter True, but the handsome sportsman is reportedly desperate for more and can't resist being cheeky around his ex-girlfriend.

A source told Entertainment Tonight: 'Khloe and Tristan are doing a great job at co-parenting together. 

'Tristan is still very flirty with Khloe and tries to get her back, but Khloe's focus is 100 per cent on True right now and showing True that they can co-parent in a healthy way, while also ensuring that she always feels very loved and supported.'

Although she's adamant she doesn't want to rekindle their relationship after she dumped him in 2019 when it was alleged that he cheated on her with her friend Jordyn Woods, Khloe still tries hard to include Tristan in family events so that they can continue to be a family.

The insider explained: 'Khloe is making sure to include Tristan in dinners, outings, play dates with True so they can have time together as a family.'

The beauty was devastated when she learned of Tristan's unfaithful ways but turned to exercise as a form of therapy. 

Khloe said on her Instagram Story in August: 'Happy Sunday everybody! I usually don't work out on Sunday but I missed days last week due to having such a busy work week and I use my workouts as a form of therapy.

'For me, they really just help me get my head right, so I'm excited. I feel like I need to get my head right, right now ... so happy Sunday.'

Despite her heartbreak, the Good American founder is 'still very loyal' to Tristan.

An insider said previously: 'Even though he has disappointed Khloe so many times, she is still very loyal to Tristan. She doesn't like when people criticize him. He will always be special to her. It's very possible that they will get back together eventually.'
