US pop star Redfoo suffered a cut above his eye and had blood streaming down his face after a man allegedly threw a glass at him in a Sydney pub on Thursday.
Redfoo, a judge on Australia's X Factor talent show, said he was celebrating the release of his new song -- New Thang -- at the bar in Sydney's up-market suburb of Double Bay when he was struck in the early hours.
"All of a sudden I was talking to some girls, and bam, something hit me in the head," the 39-year-old singer, dancer and rapper, who was treated by paramedics at the scene, told Channel Seven television.
"I just want to identify his face, so if I see him again I can say 'You're that kinda dude, who does that sort of stuff'."

"He looked at me and taunted me and winked his eye, just to say 'I got you' or something."
New South Wales state police said the alleged attacker, a 21-year-old man, was charged with malicious wounding and would appear in court on September 24.
Redfoo, whose real name is Stefan Gordy, added on Twitter that "jealousy is a hell of a drug".
The son of Motown Records founder Berry Gordy Jnr, Redfoo is best known for his electropop band LMFAO.
He added that the incident was "not a reflection of Sydney, Australia", but called for the use of plastic cups at more drinking venues.
"This is just a case of an idiot in a club."
