*Rapper Mase is caught up in a legal battle with a jewelry company over an alleged $35,000 bill.

The folks at Aydin and Company in Atlanta have filed suit against the rapper, claiming he owes them thousands of dollars dating back to 2005.

Mase – real name Mason Betha – has filed papers asking for the lawsuit to be dismissed, insisting he never signed the “alleged contract at issue,” according to TMZ.

The jewelers are seeking payment of $35,000, as well as interest and legal fees.
