Legendary comedian Joan Rivers is recuperating at a New York hospital after suffering complications during what was called a non-surgical procedure Thursday morning.

The 81-year-old host of E!'s "Fashion Police" was taken to Mt. Sinai Hospital in New York after she stopped breathing during what's being reported as "minor throat surgery".

"I want to thank everyone for the overwhelming love and support for my mother," Rivers' daughter Melissa said in a statement shortly after arriving in New York. "She is resting comfortably and is with our family. We ask that you continue to keep her in your thoughts and prayers."

Rivers was in New York to promote her new book, Diary of a Mad Diva. "She was so lively and sweet," said a source. "She even let people take photos with her. She definitely had a lot of energy!  She was cracking jokes about everyone from Jay Leno to Jackie O. She was as sharp as she's ever been."
