Another new record for LeBron James...this time off the court.

FOX News' Chris Hoenig explains:

LeBron James has signed a new lifetime endorsement deal with Nike...

It's believed to be the first lifetime deal any athlete has signed with the sportswear company and is expected to easily surpass the 10-year, $300-million agreement Nike signed with Oklahoma City Thunder forward Kevin Durant, making it the biggest guarantee they've ever given a single athlete...

(James) "Hard work on three, together on six... One, two three, four, five, six..."

Nike has featured LeBron in commercials and made 13 different versions of star's signature shoe since they signed their first $90-million deal just before he graduated high school.
