Sharon Osbourne taking one-month break

TV host Sharon Osbourne suffered a health scare last week and will take a month-long hiatus from "The Talk", says representative.

The 62-year-old co-host of the show "collapsed from mental and physical fatigue" after returning home here on May 15 after a "grueling schedule last week in New York and Toronto", Sharon's representative told eonline.com.

"Her doctors report that she is suffering from 'extreme exhaustion' and assessed that she most likely returned to work too soon after being hospitalised recently for pneumonia," the representative added.

"Sharon has been advised and has agreed to to take a month hiatus to recover fully from these recent events. Sharon would like to thank everyone at 'The Talk' for granting her this time off and to all friends, family and others for their incredible support."

Her daughter, Kelly Osbourne, 30, co-hosted "The Talk" in her place two months ago and revealed that her mother had undergone hernia surgery and later contracted pneumonia.

Sharon has battled several ailments in previous years. In 2012, she underwent a double mastectomy after doctors discovered she carried a gene that made her susceptible to breast cancer. Sharon is also a colon cancer survivor.
