Sharon, who's been co-host of The Talk since 2010, has experienced a number of health breakdowns in 2015 so far. The star underwent surgery for a hernia in March and shortly after the procedure she came down with pneumonia.

Physicians believe Sharon's most recent health scare is probably in part due to the stress from her hectic schedule.

"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," her representative said.

Sharon has been active on Twitter in the past few days, posting photos of herself with husband Ozzy and daughter Kelly.

She also managed to share some tweets in promotion of Red Nose Day, an event which benefits a host of charities.
