Alexa Ray Joel is doing fine since collapsing onstage while singing to a sold-out crowd at New York City's Cafe Carlyle over the weekend.
"I'm doing fine. I'm great, and I'm standing," the 28-year-old daughter of Billy Joel and Christie Brinkley told " Extra" on Wednesday.
"I do tend to get a little bit of a low blood sugar drop. I was working shows in a row. You know it happens, singing is a physical act. I think I was just building up my stamina and it was a lot of shows in a row. Hey, life happens."
Joel was two songs into her set on Saturday night when she lost consciousness. She was taken to the emergency room at New York-Presbyterian Hospital and later released after being diagnosed with vasovagal syncope, a non-serious condition that blocks blood from flowing to the brain and causes fainting, her rep told People.
The singer told Extra: "I really appreciate that everybody has been so respectful and not putting any salacious slant on the whole story."
She added, "Everyone has been so caring and sweet and supportive. I'm getting all these messages on Facebook and social media of everyone asking how I'm doing. I really appreciate it, it's helping me actually recover."
