Michael Phelps' historic 8 gold medals are worth a lot more than their weight in gold! It looks like Mr. Phelps just got $100 million dollars hotter.

"What is the value of eight golds in Beijing before a prime-time audience in the U.S?" asked Michael's agent Peter Carlisle. "I'd say $100 million over the course of his lifetime."

Holy moly! That's a lot of money!!!

As we told you earlier, from Beijing Phelps will travel to London to start promotions for 2012. Michael told NBC's Bob Costa to force him out of the pool if he is swimming past 30 marking London's 2012 Olympic games as Michael Phelps' last.
