Howie Mandel

Howie Mandel is "home and doing better" after fainting and being rushed to hospital.

The America's Got Talent judge told fans he was "dehydrated and had low blood sugar" when he collapsed in a Starbucks on Wednesday.

He tweeted: "I am home and doing better. I was dehydrated and had low blood sugar. I appreciate the great doctors and nurses that took such good care of me. Thank you to everyone who reached out but I am doing ok!"

Sources told TMZ how paramedics were called to the scene and took Howie to a hospital in Tarzana, California. Onlookers said the star was able to sit up by the time Los Angeles Fire Department officials arrived at the cafe.

According to insiders, the Deal or No Deal host is a regular at the branch of Starbucks.
