After getting rushed to Mount Sinai Hospital in Manhattan due to surgery complications, "Fashion Police" lead host Joan Rivers is currently "resting comfortably," Fox News reported.

While at a New York City clinic undergoing a throat surgery, which is a minor endoscopic procedure, Rivers stopped breathing.

Upon learning the incident, River's 46-year-old daughter Melissa and 13-year-old grandson Cooper took a morning flight to the city, E! Online reported.

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

One day earlier, Rivers appeared to be in good spirits while promoting her new book "Diary of a Mad Diva" at the New York City Time & Building,

"She was so lively and sweet. 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," a source told E! Online adding Rivers mentioned nothing about a surgery.

Police who responded to the 911 call told People they transported the veteran comedienne they described as an "81-year-old female" from "a doctor's office on 93rd Street to Mount Sinai Hospital in critical condition."

 "This morning, Joan Rivers was taken to The Mount Sinai Hospital in New York, where she is being attended to," the hospital's spokesperson Sid Dinsay confirmed in a statement.

"Her family wants to thank everybody for their outpouring of love and support. We will provide an update on her condition as it becomes available," Dinsay added.

In July, Rivers made headlines after cutting short a CNN interview with Fredricka Whitfield and walking out on set.

The incident was spoofed by David Letterman who walked out when Rivers appeared on his show.
