Steven Tyler blames food poisoning for his accident in the shower earlier this week.
The 63-year-old rocker was forced to cancel a show in Paraguay on Tuesday after sustaining injuries to his face, which he says occurred when he "passed out" as a result of the nausea he was suffering.
He told Today: "I started to get sick, and I just fell on my face. I just passed out."
The Crazy hitmaker has previously battled alcohol and drug addictions and can understand why people may have assumed his fall was due to overindulgence.
He said: "I get that people think that. It still bothers me a little, but it's something that I have to have to deal with for the rest of my life."
