Joan Rivers' Family 'Keeping Fingers Crossed'
Joan Rivers' daughter has said the comedian's family are "keeping our fingers crossed" as she remains in a serious condition after suffering a cardiac arrest.
The 81-year-old has been in hospital since Thursday after her breathing stopped during a vocal cord operation at a Manhattan clinic.
In a statement released by Mt Sinai Hospital, the star's daughter Melissa Rivers said: "Thank you for your continued love and support.
"We are keeping our fingers crossed."
There was no update released as to Rivers' condition.
Rivers is considered a pioneer for women in stand-up comedy. The Brooklyn native, who graduated Phi Beta Kappa from Barnard College, played the comedy club scene in New York in the 1960s.
In 1983, she earned one of the biggest jobs in the business when then-Tonight Show host Johnny Carson crowned her as his regular guest host.
But her subsequent, short-lived stint hosting a competing late night talk show on Fox network in 1986 led to a rift with Carson that lasted until his death in 2005.
She went on to host an Emmy Award-winning daytime show, The Joan Rivers Show, and more recently has found a niche on the awards show circuit, turning her biting wit on the fashion faux pas of Hollywood celebrities.
Rivers, known for her penchant for plastic surgery and with a reputation for being a ceaseless worker, has also starred alongside her daughter in the WE TV reality show Joan & Melissa: Joan Knows Best?
