Floyd Mayweather vs. 50 Cent Beef Over Amid Trey Songz 'Cheating Scandal' Diss? Instagram Support (Distasteful Blast) After Stephanie Moseley & Earl Hayes Murder-Suicide

The dramatic "feud" between undefeated boxing champ Floyd Mayweather and rapper 50 Cent is officially over. At least for now, during this time of shocking tragedy...

Reports confirm that earlier this month, aspiring emcee Earl Hayes shot and killed his "Hit The Floor" wife Stephanie Moseley before ultimately turning the gun and taking his own life. Hayes was a loyal member of Mayweather's Money Team, and rumors suggest that the infamous fighter witnessed the disturbing murder-suicide on Facetime Chat. Following such sorrowful news, the Get Rich Or Die Tryin' superstar expressed his heartfelt sympathies for Mayweather on Instagram. All issues aside, the two will always be friends:

50cent: "RIP Hayes, @floydmayweather you are my little brother. All can think about is what you said to me up stairs. Don't you ever do nothing to your self no matter what champ. We can fall out and fight or what ever,but I don't want to see you go out like that. #SMSAUDIO #POWER #FRIGO."

Mayweather later re-posted the touching message.

But of course, Fifty still had to stir-up some online controversy...

Apparently, Hayes may have killed Moseley out of anger and jealousy - because she was allegedly having a "secret" affair with hip-hop crooner Trey Songz (among others).

And the G-Unit hypeman just couldn't keep quiet!

Following Moseley's unfortunate death, Songz tweeted:

@TreySongz: "R.I.P babygirl. Once an angel on earth, now watching over us from Heaven. You'll b missed but never forgotten. Love."

Fifty's rather distasteful post was later deleted.

So, is yet another Hollywood "beef" brewing within the industry during this time of brutal tragedy? Stay tuned...

Thoughts and condolences go out to the VH1 beauty's family, friends, and fans during this sad time. RIP, Stephanie Moseley.
