Chris Brown has been left with a bloody gash on his chin after a reported fight with rapper Drake. The pair are said to have clashed in a New York nightclub and the R&B star was treated in hospital after he was allegedly bottled by one of the rival hitmaker’s entourage. The singer posted a gruesome snap of his injury on his Twitter page, but later removed it. The two musicians have had a long-running feud over Drake’s dalliance with Chris’s ex Rihanna. But when they met at WIP club Wednesday night, Chris is thought to have sent a bottle of champagne to Drake's table as a peace offering. Unconfirmed reports say the bottle was returned with a note referring to Rihanna which read: “I'm f****** the love of your life, deal with it." Chris then flew into a rage and confronted Drake, who threw a punch. Before the Turn Up The Music singer could retaliate, onlookers say another man hit him in the face with a bottle. Security broke up the fracas and Drake left with his entourage, according to website MediaTakeOut.com. Chris, who showed the bleeding chin to his ten million followers before changing his mind, then took himself to hospital. He later tweeted: "How u party wit rich n**** that hate? Lol... Throwing bottles like girls? #shameonya!" Furiously venting on Twitter with a series of posts that he subsequently removed, the singer also wrote: "N****s in the bathroom b**ch a** n****s." The 23-year-old split with Rihanna in February 2009 after he assaulted her in a violent row before the Grammy awards. Despite their rivarly, an unreleased track featuring both Chris and Drake called Yamaha Mama surfaced online last month.
