This is the ultimate power lunch -- a table for three with the guy who co-created Def Jam, the guy who directed "Iron Man" and the guy trying to colonize Mars.

Elon Musk, Jon Favreau and Rick Rubin all met for lunch Sunday on the Malibu Pier.

Favreau has mentioned his friendship with the SpaceX and Tesla Motors CEO in the past, saying he based "Iron Man's" Tony Stark on Musk. No word on how they both know Rubin, but there is a Def Jam film in the works.

Just how powerful was this meal? Check their reported net worth stats: Rubin, $250 Million ... Favreau, $60 Million ... and Elon Musk, $13.2 BILLION!

So, who picked up the check? The correct answer is: It doesn't matter.
