Over the weekend, Kevin Federline, ex-husband of Britney Spears, fell ill and was admitted to the hospital as his heart showed signs of distress, TMZ reports.

Federline was in Australia filming scenes for an upcoming reality show entitled "Excess Baggage." He was playing football at the time of his medical scare, according to TMZ.

At six feet tall and weighing in at 231 pounds, "KFed" has been under scrutiny for his weight gain in the past but it is unclear whether or not the heart scare is related to his blossoming obesity. He was admitted for observations overnight and was spotted wearing an oxygen mask earlier today.
