Joan Rivers' family have confirmed the comedian is on life support after going into cardiac arrest last week during a procedure at a doctor's office.

Her daughter, Melissa Rivers, said in a statement that her mother is on life support "at this time."

Melissa said the family is extremely grateful for the public support.
