Washington, Sept 19: All those Britney Spears fans who don’t approve of her hubby Kevin Federline only need to put up with him for another 26 years, for that’s how long he’s predicted to live.

Blender Magazine, in its October issue, estimates the number of years the aspiring rapper is likely to live.

And, based on Federline’s age, height, smoking habits, alleged love of alcohol, marijuana and reported body odor, the number they’ve come up with is the age of 55.

While some years are added onto Federline’s age thanks to his dancing and for not being a "shallow mother[bleep]", there are more years to be lost for abandoning his pregnant girlfriend, and mother of his two eldest kids, Shar Jackson for Britney.

At the moment, K-Fed is busy with parenthood, having become a dad for the fourth time, as well as trying to get his rapping career off to a decent start.

Gerontologist Dr. Demko writes in the issue that Federline can add on another 16 years if he gives up his “smoking, booze and drugs”.

"Kevin will also need the common sense to ditch the smoking, booze and drugs, which will give him 16 more years to enjoy Britney's money and watch his four (and counting) kids grow up," TMZ.com quoted Dr Demkio, as stating. (ANI)
