Singer Alexa Ray Joel, daughter of music legend Billy Joel and supermodel Christie Brinkley, was feeling fine Monday after fainting onstage Saturday, the final night of her April 1-12 engagement at Manhattan's Café Carlyle.

"I wanted to thank everyone for coming out to support me," Joel, who was treated at NewYork-Presbyterian Hospital and released, said in a statement. "I was excited and determined to fulfill my final performance and I really wanted to end my run with a bang, but this was not what I had in mind and [I] hope I have the opportunity to make it up to the wonderful audience very soon. Thanks for all the concern."

Her spokeswoman, Claire Mercuri, told The New York Times' Artsbeat blog Joel had suffered vasovagal syncope, one of the most common causes of fainting. A typically harmless condition, it triggers a sudden drop in heart rate and blood pressure, leading to reduced blood flow to the brain and a brief loss of consciousness.

Joel, 28, "had taken ill earlier in the afternoon and announced from the stage that she pulled out her back and neck, but wanted the show to go on," Mercuri added.
