Khloe Kardashian and ex-boyfriend French Montana have sparked a rumor frenzy that they are seeing each other again, after being photographed together in Miami. The on again and off again couple were caught on camera showing some PDA during the Ultra Music Festival.

People magazine reported that the couple were spotted last Saturday holding hands while taking a walk by the dock. When the two sat down with a group, Montana was photographed with his hands resting on Kardashian's knee.

The "Keeping Up With The Kardashians" star and her ex-boyfriend went to a Miami nightclub called Ivy later on in the evening.

Khloe even posted a photo of their vacation on her Instagram account. With the caption, "The Ciroc made us do it!! #StepIntoTheCircle," she posted a photo of her and her friends clowning around.

It will be recalled that Khloe Kardashian and French Montana first started dating in May last year, but called it quits soon after.

But paparazzi have caught the pair still spending time with each other even after their breakup.

Last March, the two were also photographed together on a vacation in Key West, Florida. They stayed in Sunset Key, which is a luxury resort.

People magazine's source also reported that the alleged couple looked quite happy being in each other's company.

During the episode of "Keeping Up With the Kardashians" this week, Khloe and French's relationship was again in the spotlight when the two bumped into each other in Las Vegas.  

Khloe was with her best friend Malika Haqq when their group chanced upon French Montana in the same club. But while Khloe seemed okay with the encounter, her best friend was not happy about it.  

"It's a girls' trip," Malika said. "I don't want it to be ruined by Khloe's ex."

Previous reports said that French Montana actually blamed Malika for ruining his relationship with Khloe, and according to fans, this might be the reason why Malika was not thrilled bumping into her best friend's ex-boyfriend.
