Chris Paul's friends and family are doing it BIG for his belated SURPRISE 30th birthday bash Saturday night ... flying in Lil Wayne from Haiti to perform for a bunch of his closest friends ... TMZ Sports has learned.
Paul's birthday was actually in May ... but we're told Paul's family pushed off the celebration because he wanted to wait until after the NBA playoffs were over.
Sources connected to Paul tell us ... the NBA star's family is sparing no expense on the party -- we're told it's already running north of $200,000!
Among the expenses, we're told Paul's people paid for Wayne's private jet from Haiti -- where the rapper put on a free concert with Chris Brown and boxer Andre Berto.
As far as the guest list for Paul's big 30, we're told all of the Clippers are invited -- including DeAndre Jordan -- and all of Young Money.
Last year, Paul got an autographed pic from his hero Tiffani Thiessen. Wonder how he'll top that this year?
