Tokio Hotel guitarist Tom Kaulitz has revealed he suffered a two-day erection after taking too much Viagra.

Kaulitz was quoted as telling the German newspaper Bild he experimented with the anti-impotence tablet during a tour of Asia.

“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. I popped one in,” Kaulitz said.

The guitarist admitted that he then took “probably too many” tablets when he arrived back at his hotel, reports the Metro.

“The next morning my head was pounding and everything in front of my eyes was blurry. It wasn't fun anymore. It was pretty bad,” he said.

Kaulitz added: “Unfortunately there were situations where it just wasn't appropriate.”
