Khloé Kardashian, French Montana Dating Again! Spotted Partying With Diddy, Cassie at Miami Nightclubs Over Weekend

It looks like on-and-off couple Khloé Kardashian and French Montana are dating again! The two stars were spotted getting cozy in Miami over the weekend at nightclubs with fellow celebs Diddy and Cassie.

A source told E! News that the four of them arrived at the Red Bull Guest House together, and later Kardashian and Montana ventured off to spend some quality time alone by the pool.

"They were acting very much as a couple," an insider said. "French is all about Khloé and can't keep his eyes off of her. Khloé looks really great and fit. They are all enjoying their night so far!"

Later in the weekend, the pair partied at the Hennessey V.S. party at nightclub Dream in Miami along with Diddy and his son Justin.

As the party heated up, DJ Funkmaster Flex began playing some of French's songs and French rapped along from his seat without leaving Kardashian's side.

Diddy posted a pic of the group at another party with the caption, "We're everywhere!! My Real True Badboy Family let me know you out there."

The pair crashed at Diddy's Miami mansion while visiting.

Things are looking up for the couple following a breakup late last year, when Kardashian had second thoughts about rushing into a relationship so soon after her breakup with husband Lamar Odom.

But this wasn't the couple's first recent Florida vacation. The two quietly vacationed in Key West earlier this month.

"Khloé and French were very low-key when they visited Sunset Key," a source told People about their stay. "They kept to themselves. They spent much of their time barefoot and happy, soaking up the sun and looking completely comfortable together."

It's especially good news to Montana, who was very public about his affection for Kardashian even after their breakup.

"Our relationship -- you break up, you make up, you break up, you make up," the rapper said. "We went through that a couple times. You never know."
