New Reality Show for Big Brother's Brachel?

Turns out ... when Rachel told our photog on Thursday night that she was getting married THIS weekend, well ... that was just the alcohol talking. Sources close to Rachel tell TMZ they have no plans on a quickie wedding, but they do want to settle down in Los Angeles (Brendon is currently enrolled in grad school at UCLA).

We're told Rachel is planning to use her "BB" winnings to buy a condo in town, look for opportunities in the entertainment biz, and plan her wedding.

And according to our sources, "planning her wedding" entails pitching it as a reality show to various production companies and networks in hopes of having it all paid for.
