50 Cent vs. Tony Yayo Beef, G-Unit Feud Reignited? Rapper Slams 'RIP Chris Lighty' Instagram Tribute, 'Why Shouting Mike Lighty B*tch A$$ Out?' [PHOTO]

Rapper 50 Cent is on the cyber attack once again. This time, Fifty ousted fellow G-Unit emcee Tony Yayo on Instagram for giving a viral "shout-out" to well-known hip-hop promoter, Mike Lighty. So, what's up with that?

Lighty's brother Chris was an established music executive who helped co-found the popular marketing/management company and record label, Violator. The renowned 44-year-old businessman was discovered dead from an apparent suicide in his Bronx apartment back in August 2012. His brother and several family members still do not believe that the tragic gunshot wound was suicidal, and an investigation is still underway. In fact, Fifty (who worked closely with Lighty) supports such claims, and even hired his own legal team to uncover more details surrounding the incident.

So - what does this have anything to do with Yayo?

Earlier this month, the 36-year-old Queens native shared this "RIP" tribute on Instagram in honor of "Throwback Thursday" -

tonyyayo: "TBT RIP Chris Lighty @mikelighty [pray]."

But for some reason, Fifty was confused why Yayo even mentioned Mike in the comment:

50Cent: "Yayo why you shouting Mike b*tch a$$ out?"

Why was the Get Rich Or Die Tryin' superstar even creeping in the first place?!

Apparently there's no hard feelings, however. Yayo later posted:

tonyyayo: "MJE boyz... Passport Gang."

But this isn't the first time the Street King Immortal rapper called-out his fellow crew member. Fifty once compared Yayo to "spoiled milk" for appearing on a track with Troy Ave (during a Hot 97 radio interview last year, via Design & Trend).

Yayo later responded on Twitter with:

@TonyYayo: "As much bullets I took for G-Unit. My moms crib shot up, almost killed my sis and my niece... Now I'm compared to milk. I made that brand."

After things eventually settled-down, Yayo told Ebro in the Morning:

"I did get emotional on Instagram. That's my first time. But these are my brothers. I had a lot of frustration that year... I had feds knocking on my door. All kinds of crazy things going on. I'm not the average - I don't live the average rapper's life - so I got emotional. And you know, 50's crazy... It's almost like he's not human sometimes."
