Miley Cyrus -- I Got My Pet Pig Hookup From the King of Fake Teeth

Exclusive Details

Miley Cyrus
's business deal with the king of fake buckteeth really helped her bring home the bacon -- as in her pet piglet Bubba Sue. 

TMZ has learned the micro pig Miley's been showing off in pics since August ... was a gift from her business partners at Billy Bob Products -- the company that just started cranking out those ridiculously popular Miley Bob fake teeth for $11.99 a pop. 

Billy Bob founder Jonah White tells us he and his wife reached out to Miley back in August ... after her dog Floyd died, and set up a backstage meeting in St. Louis. He says that's when they surprised her with Bubba Sue -- complete with a birth certificate.  

Around the same time ... Jonah and Miley also hammered out their business deal. Sources close to the negotiations tell us Miley is getting a 50/50 split of the profits from her line of fake teeth.

Sweet deal, sweet pig.
