Having a lot of money doesn't mean you have to be a jerk.

"To be successful, you don't have to be an asshole," legendary rapper and "Law & Order" star Ice-T told TheStreet about what he has learned from being around billionaires Richard Branson and Mark Cuban. Ice-T and his wife Coco Austin, a successful entrepreneur in her own right, were at a New York City TGI Fridays promoting the return of the chain's Endless Apps deal and several new cocktails. "I think you can be successful and be cool as hell," the actor added. 

Branson and Cuban may be able to learn a thing or from Ice-T as well. 

Ice-T is no stranger to money in his own right, having likely raked in a good number of greenbacks throughout his illustrious music career and starring role on the popular "Law & Order." So, when the star drops some wisdom on investing, one may want to take notes.

"Investing is gambling, you are taking a risk - you have the money, you can put it in a shoe box or the bank, but you have decided to take a risk to [try and] double your money quicker,", said Ice-T, adding that "the bank is a good investment."

Ice-T said he likes to invest in himself by developing new albums or other content (which could create more money). As for pleasure, the actor says he likes buying watches and cars, but concedes "I am not going to make any money off of that stuff, those are just things I enjoy buying."

He also serves up a cautionary reminder to those who may be getting giddy right now about rising asset values of all kind -- from stock prices for Apple (AAPL - Get Report) and Facebook (FB - Get Report) to land in Florida.

"I invested in real estate and lost my shirt when the bubble popped," Ice-T said.
