Ever 50 Cent introduced his new brand of Vodka, Effen, he's had to go head-to-head with the other big brand of vodka owned by a New York hip hop mogul. Diddy's Ciroc has been around longer than Effen, thus making it a more established brand, but Fif's tried his damnedest to drum up some notoriety with a #NoPuffyJuice campaign on Instagram. Last night, Diddy fired back with a backhanded birthday wish to 50. 

Jokingly announcing that he'd bought Fif a lifetime supply of Ciroc, Diddy was quick to make it clear that he was just playing. What with this and Fiddy's recent clash with French Montana over Ciroc, though, it looks like competition could still be pretty stiff.
