50 Cent vs. Diddy Beef Escalates: French Montana Instagram Diss After Summer Jam Reunion, 'Never Forget Who Was There For You When No One Else Was'

Rapper 50 Cent's rather harsh on fellow hip-hop mogul, Sean "Diddy" Combs. Apparently, the "I Don't Wanna Know" emcee is "too old" to make good music anymore. Diddy's exclusive vodka brand Ciroc is nothing compared to Fifty's Effen. Oh, and the G-Unit hypeman thinks that the Grammy Award winner might have some homosexual tendencies.

So obviously, they're not the best of friends!

Which is also why Fifty's currently beefing with loyal Bad Boy Records singer, French Montana. But several fans were shocked when both rivals hit the stage alongside Chris Brown at Hot 97's annual Summer Jam concert over this past weekend.

The performance was amazing, but perhaps Diddy felt somewhat slighted?

Just a few hours after the surprise guest appearances, Diddy shared this cryptic message on Instagram:

Did he just throw major shade at Khloe Kardashian's rumored boyfriend (for kicking it with Fifty)?

Several followers still think Diddy could likely be talking about longtime girlfriend, Cassie. He later shared this rather motivational post:

Meanwhile, Fifty's in a rather positive cyber mood, too:

50cent: "Good morning let today be the day you begin to make steps towards your Goals. No more bullsh!ting make it happen, let's get to it."

Apparently, security intially refused letting members of G-Unit into the venue. Well, the "Candy Shop" superstar wouldn't let that fly - maybe that's why he called a truce with Montana?

50cent: "They didn't even want to let us in SUMMER JAM, They searched us till I looked around and said, (the Fvck yal think we the Isis group).Shout out to CB he killed it."

The "Ocho Cinco" rapper basically treated the monumental "reunion" as a joke:

frenchmontana: "Even @50cent couldn't hate tonight lol I love your dance moves play boy 'puff voice' we did it for Chinx tonight #younglegends."

Maybe these guys strive off of the drama...
