HE IS best known as pop superstar Britney Spears’ ex-husband, but now Kevin Federline is carving his own path.

The former backup dancer, nicknamed K-Fed and then K-Fat by the tabloids after his weight blew out dramatically, is one of the competitors in Nine’s new reality show, Excess Baggage.

33-year-old Federline made headlines around the world last week when he collapsed and was hospitalised while filming a challenge with the Greater Western Sydney Giants AFL team in Sydney.

It was the second time the father-of-five suffered a health scare during the shoot. He was also admitted to Karratha Hospital in December.

He said he was “terrified” during last week’s collapse.

“One of the reasons why I’m doing this is because I don’t want to worry about episodes like what happened on Monday,” he said.

“The whole thing just makes me real cautious about what I’m doing and what I’m putting my body through.”

K-Fed will answer PerthNow readers’ questions about his weight gain and loss, his health scare, life as ‘Mr Britney Spears’ and his future career plans on Tuesday at 2:30pm.
