Raz B — BOTTLE TO THE FACE … Singer Hospitalized After Nightclub Attack

Exclusive 0815_raz_b_wmRaz-B — the former B2K singer — was hospitalized in China yesterday after someone smashed him in the mouth with a glass bottle … turning his face into a bloody mess.

The 28-year-old R&B star was performing at a nightclub in Zhejiang (birthplace of Qian Xuesen — the “Father of Chinese Rocketry” … yay science!).

Raz”s rep tells our sources … during the performance, he noticed a fistfight in the crowd and went to go break it up — when someone swung a bottle right into his moneymaker, causing several cuts … including a deep gash on his lip.

We”re told the Chinese police immediately stepped in … grabbing the attacker AND Raz — and dragging them both to jail.

Cops quickly released Raz after determining he did nothing wrong. Raz”s rep says cops made the bottle thrower fork over roughly $5,000 to pay for Raz”s medical expenses.

After the drama at the police station, Raz was finally taken to a hospital, where he underwent a 1-hour surgical procedure to repair the “hole” in his lip. The wound also required 4 stitches.

Raz issued a statement to our sources saying, “F**k this s**t hurts. I have a f**king hole in my lip. Thank god I made it to the hospital.”

Raz — who”s been in living in China for the past 3 years — says he doesn”t plan on pursuing legal action. He also says he plans to move back to the U.S. before the end of the year to focus on a “big comeback.”
