Kevin O'Leary -- Courtney Loves Making Money ... And So Do I

EXCLUSIVE

Kevin O'Leary and Courtney Love definitely made a connection -- not romantically, but financially -- during their marathon dinner date Tuesday night.

Mr. Wonderful came on TMZ Live to reveal their nearly 4-hour meal was all about money and music. Courtney has publishing rights to tons of music -- hers and Kurt Cobain's -- and, of course, Kevin's got tons of money.

Kevin says he's considering investing in her music catalog, but you have to see what really shocked him about Courtney.
