When it comes to her hair, Ke$ha has always gone to extremes -- but this takes the cake!

After shaving off the side of her head in January, the glitter-loving singer, 24, glued several unusual accessories to her head: more than 25 gold studs!

"It's happening," the "Blow" singer wrote in a Twitter caption Tuesday. "I look like a homeless clown right now."

The singer, who celebrates her 25th birthday Thursday, is currently working on her sophomore album, due this spring. "I'm gravitating toward making a solid c-ck rock record," she told Rolling Stone in 2011.
