LeBron James Belts Out New Diddy Songs, Almost Nails Lyrics!

LeBron James is giving his personal review of Diddy's new project ... and it's safe to say the rap mogul got the King's approval -- 'cause Bron actually took the time to learn the lyrics!!

Well ... some of them.

The Los Angeles Lakers superstar is infamous for his backseat jam sessions whenever new music drops ... and it was only a matter of time before he gave his two cents on the Bad Boy founder's latest effort -- "The Love Album: Off the Grid," which dropped last week.

Bron went through three of his favorite tracks -- "Pick Up," "It Belongs To You," and "Brought My Love" ... vibin' out as each tune blasted in his Maybach.

James even tried his best Jacquees-esque falsetto at one point ... singing along until a fast-cadenced part of the song seemed to catch him off-guard.

The four-time champ rolled with the punches, though ... pretending to crush each word. In reality, it was more like the time he tried to do karaoke to a 6lack song.

"Man O Man!!!!!!!," James captioned his vid ... calling the project "an ABSOLUTE FKN STONE COLD VIBE!!!!!"
