The 28-year-old rapper whose real name is Dwayne Michael Carter Jr. was in suburban St. Louis Sunday for a performance at the outdoor Verizon Amphitheatre. KTVI-TV reported that Lil Wayne, accompanied by a large entourage, showed up Sunday at DePaul Health Center's emergency room.
Hospital spokeswoman Jamie Newell said she could not confirm Lil Wayne was at the hospital, citing privacy laws. But Lil Wayne wrote about it on his Twitter account.
"The Lou was good but I busted my ... head at the sk8park! 9stitches! Gnarly gash over my left eye! Luv the people," he wrote.
Messages left with Lil Wayne's management on Monday were not returned. Details about how he was hurt, and where, were not immediately available.
Lil Wayne is about to release his new album, "The Carter IV." A previous album, "The Carter III," was the best-selling album of 2008 and the Grammy Award winner for best rap album of that year. In 2010, he served time in a New York jail after pleading guilty to a weapons charge.
"The Carter IV" will be released digitally after Sunday's MTV Video Music Awards, at which Lil Wayne will perform. The album, which features collaborations with Drake, Cory Gunz, Rick Ross, Busta Rhymes and others, will be in stores on Aug. 29.
