Steven Tyler's not looking too pretty after passing out in his shower on Tuesday in Paraguay and suffering a black eye, cuts to his face and the loss of two teeth. I was a little skeptical about this picture but the bruises match what you see in the live video.

His tour manager called the American embassy Tuesday to find the best hospital and once there he was stitched up and had dental implants put in. The dentist, Dr. Maria Bastos, said he was "friendly and humble... He surprised me with his cheerfulness." Tyler blames the fall on dehydration caused by food poisoning. As a result, Aerosmith postponed their show that night, but made it up Wednesday.

Aerosmith guitarist Joe Perry was also proud of Tyler, saying, "He's amazing... a real trooper. [He] even played harp with his busted lip. My mind was blown. He put on one of his best shows ever."

Yesterday (Thursday), Tyler spoke with Matt Lauer on NBC's Today show saying, "Short of having my legs taken off, people are going to expect me on stage no matter what. I went out on stage and I wore my sunglasses for the first song. I took them off and the crowd roared." When asked if wasn't dehydration that caused him to pass out, rather than a drug relapse, Tyler said, "Being in the program, it's something we have to expect. I went public with my problems only to address them head on. You know, people thinking that is natural and normal, [it] still bothers me a little. It's something I have to deal with the rest of my life."

The tour moves to Argentina tonight (Friday) and then onto Sao Paulo, Brazil on Sunday.
