New dad Owen Wilson is turning 50 on Nov. 18 – and Breaking Celebrity News has learned exclusively his party in Hawaii promises to be a who’s who of Hollywood royalty.

“Owen is plotting a millionaires’ birthday bash with best pal Woody Harrelson and everyone wants an invite,” an insider told Breaking Celebrity News. “The plan is to use both his and Woody’s Maui homes to turn it into the ultimate showbiz event.”

It’s been a year worth celebrating for Wilson, who as Breaking Celebrity News readers know, just welcomed baby daughter Lyla with model Varunie Vongsvirates. And money for the big birthday blowout is no object when it comes to entertaining some of Hollywood’s biggest names.

“He’s invited all of his A-list buddies months in advance, with Jennifer Aniston, Ben Stiller, Julia Roberts, Ellen DeGeneres, Vince Vaughn and Bill Murray all on the guest list.”

Of course, brothers Luke and Andrew will be there too. In fact, Owen’s even footing the entire bill, to make sure his guests want for nothing.

“Owen is making it a three-day, all-expenses paid event on the beach for his famous guests,” the insider revealed. “He’s going all out and it’s already shaping up to be the hottest party of the year!”
