French Montana and ex Khloe Kardashian partied together at the GQ x Armani Grammys after event sponsored by Patron, along with the "KUWTK" reality star's BFF Malika Haqq.

Khloe Kardashian, who hosted E! Grammys after-party, arrived to the event with sisters Kendall and Kylie Jenner.

"Safe to say this sighting is bound to reignite those romance rumors," E! News commented on French Montana and Khloe Kardashian hanging out at the party.

"Khloé flaunted her enviable gams in a sexy beaded dress with a super-high slit while Kendall rocked a long black dress with lace detailing," the article added. "Kylie, meanwhile, seemingly channeled sister Kim with a sexy white sequin number that perfectly hugged her curves."

A source told the website that during the party, French Montana was only just a foot or so away from where Khloe Kardashian was while she talked to her friends.

The source added: "Khloé was animated, laughing, and joking waving her hands in the air with the story she was telling. French had his arms folded on the bar leaning up against it chatting to his friends, and would look on to Khloé every once in a while."

Adding fuel to the fire was the report Mail Online that Khloe Kardashian went to Hooray Henry's club in Santa Monica, California to watch her ex-boyfriend, French Montana, perform.

"The couple ended their relationship in September last year after seven months of dating," said Mail Online. "They briefly reconciled in November, but things quickly fizzled out."

The Grammys after-party was attended by rapper Meek Mill and his rumored girlfriend Nicki Minaj, Chris Brown and Justin Bieber. French Montana and Khloe Kardashian didn't seem to be avoiding each other despite the presence of the paps. At one point, the former couple even took a photo along with Meek Mill who was sandwiched between them.
