'Idol's' Randy Jackson to LeBron James, Just Take My Money

LeBron James just boosted the price of L.A. Lakers tickets in a HUGE way -- with rich stars like Randy Jackson admitting they would pay a bloody fortune to see Bron play at Staples Center.

"[I would pay] anything to see LeBron, dude ... one of the greatest players ever," the former "American Idol" judge just told us outside of Craig's in L.A. ... "I love him. I can't wait to see him."

By the way, season ticket prices on sites like StubHub have reportedly doubled since the announcement about LeBron ... with one buyer paying close to $200,000 for the upcoming season.

Also, Jackson said he'd love to work with LeBron if The King wants to get into music while he's in L.A. -- so, dude's got options.
