Sean Kingston is LYING through his pearly white teeth … ’cause Justin Bieber DID NOT

“gift” him his customized Fisker Karma … TMZ has learned.

Kingston began the charade in front of Boa this weekend … when he rolled up to the steak joint in

JB’s  chromed-out car and told photogs Justin had given it to him as a gift … as a perk of their

friendship.

But sources close to the The Biebs tell TMZ Kingston’s pants are COMPLETELY on fire — truth is,

Sean asked Justin if he could BORROW the car to go to dinner since Bieber is on tour … and Justin

obliged.

Now, the car is back in Justin’s garage — and we’re guessing Kingston’s driving privileges have been

suspended indefinitely.

Kingston’s people say he was just joking when he said JB gave him the whip … right, and Lindsay has

walking pneumonia.
