Pecker problems for young singer

20-year-old Tokio Hotel singer, Tom Kaulitz, took a little too much Viagra one day and ended up with a never ending boner.

While on tour in Taiwan, Kaulitz said a street vendor offered him some blue pills. "I first asked the seller 'Do I look like someone who needs help with that?' He said 'no' - but that I should nevertheless try it out," the singer told Germany's 'Bild' newspaper. '[So] I popped one in."

The star decided to take a few more once he returned to his hotel - but he soon regretted his actions when he woke up.

He said, "I popped a few more pills, probably too many. The next morning my head was pounding and everything in front of my eyes was blurry. It wasn't fun any more. It was pretty bad."

Duh! If you don't need it in the first place, maybe one will do -- especially if you buy it off the street.
