Paris Hilton wants to give you the jeans off her backside -- and you don't even have to buy her a drink first!

Sources tell TMZ that the former jailbird flew to San Francisco on Wednesday for a top secret meeting with Macy's executives to discuss her new denim line. Let's hope they're not crotchless! We're told the reaction from Macy's was amazing, so expect to see Paris jeans at a mall near you -- in sizes Small, Emaciated and Nicole.

Paris used a post-prison photo-op to debut her namesake jeans outside the Lynwood jail last month.
