BEEF: Floyd Mayweather & 50 Cent Go At It On Twitter, Rick Ross Joins In!!

 You never know in the world of 50 Cent, who has used "beef" to promote in the past, if the fighting is actually real or not....But last night 50's new rival and former BFF, boxer Floyd Mayweather, took things to a new level on Twitter.

50 Cent challenged Floyd to fight other boxers, who 50 says Floyd is afraid to...and things got HEATED.

GAMBOA WANTS TO FIGHT FLOYD. I will put up a extra 20 million for the winner. He don't like it that Floyd pulled out.

GAMBOA is the truth, FLOYD no that, stop tricking and Fight

Floyd responded with some fighting words of his own, posting photos to mock his former friend, 50 Cent...

A male boxing groupie.. hold my belts because your album sales have declined http://instagr.am/p/Rjhoa1R3Vb/

Floyd took it further with,

Hold my money Fuck Boy http://instagr.am/p/RjmsFWx3Yg/

and THAT'S when 50 Cent's other rival enemy Rick Ross chimed into the Twitter beef ...

That boy @FloydMayweather said "hold my money fuck boi" haaaaaaaa #Tmt #MMG #oilmoney

50 responded with...

MONEY Floyd you know I have more MONEY then you.Al Haymen got you on a Allowance, you go broke every fight stupid.

Floyd took another jab at 50, making the pot even more interesting, when he ended it with...

YMCMB + Maybach Music + The Money Team collaborating on some new music.
