It's not just good to be LeBron James -- it's also AWESOME to be his body double -- so says LB's real life stand-in who tells TMZ Sports even LeBron's backup lives a 1st class life!!!
We spoke with Sheldon Bailey -- a 6'6" former college basketball player turned actor -- who's been LeBron's body double in commercials for Kia, Nike, State Farm and more for about 6 years.
You gotta watch the clip ... Bailey gets everything from 1st class travel, to 5 star hotel stays ... and all the awesome high end clothes he could ask for just for being connected to LBJ.
