Tila Tequila -- I Got a Big Check For My New Bedroom Partners

Tila Tequila is about to cash a huge check ... but it's not for another sex tape.

TMZ has learned she’s headed to ‘Celebrity Big Brother: US vs. UK’ and sources tell us she's getting around $175,000 for the month's worth of work.

We're told she leaves in a couple of weeks to start filming the reality show abroad with her new housemates.
