Khloe Kardashian and her former boyfriend, French Montana, were recently spotted partying at the Red Bull Guest House in Miami, once again giving rise to speculation that the two may be back together, E! News reported Thursday. The news comes a week after Hollywood Life reported, citing a source, that the reality TV star cannot make up her mind if she wanted to “proceed” with her marriage with Lamar Odom.

Kardashian and Montana were reportedly accompanied by their friends -- Sean Combs, popularly known as Diddy, and Cassie Ventura -- in Miami. Diddy shared a short clip on Instagram on Thursday that featured Kardashian and Montana. The two have been in an on-again, off-again relationship since they split in September 2014.

"They were acting very much as a couple," a source told E! News. "French is all about Khloe and can't keep his eyes off of her," adding, "Khloe looks really great and fit. They are all enjoying their night so far!"

In the last few months, several reports have surfaced of reconciliation between the two after they were spotted together on different occasions. Earlier this month, the “Keeping Up with the Kardashians” star and the 30-year-old rapper were seen getting close during a vacation in Key West, Florida, along with friends -- actress Malika Haqq and rapper Chinx Drugz.

Last week, a source told Hollywood Life that Kardashian was "stuck in the ‘unknown’ stage," and "doesn’t know what the future holds for her and Lamar. She can’t make her mind up on how to proceed with her marriage." The source also claimed Kardashian is spending time with Montana because she wanted Odom to step in.

“She’d much rather him do something completely grand and spontaneous,” the source said, adding that she is also “scared to give him all her heart again.”
