Amidst all the news and conjecture about Lil Wayne’s health, another major rap story is exploding tonight. Gucci Mane and Waka Flocka Flame — friends, frequent collaborators for years, and partners in the 1017 Brick Squad crew — are apparently embarking on what could be a bitter feud.

About an hour again, Gucci tweeted this: “Waka flacka flames officially dropped off brick squad 1017. Big Guwop say give me a offer fa this disloyal lil nigga.” Flocka reportedly Tweeted back, “Somebody tell Gucci Mane 2 SUCK A DICK.” He’s since deleted that tweet, though, and replaced it with this: “We BSM.” Also, this: “Can’t tweet beef #HucciKnowHowIrOck.”

Gucci and Flocka have had problems in the past; Flocka’s mother Debra Antney used to manage Gucci, and they’ve gone through periods where they haven’t been speaking to each other, but it’s been nothing like this. From the way things look, Brick Squad, a rap crew that’s been absolutely on fire lately, is in serious danger of shattering into pieces.
