*Grammy winner Bruno Mars wants out of his contract with publisher, Bug Music, Inc., and has sought help from a judge, reports TheWrap.com.

In a lawsuit filed in Los Angeles County Superior Court Tuesday, Mars — born Peter Hernandez — says his contract with Bug ended on May 12, 2011 because the publisher didn’t exercise its option to continue it.

Mars’s lawyer, Michael J. Niborski of the law firm Pryor Cashman LLP, wrote that Bug initially acknowledged that Mars fulfilled his part of the contract, and that in order for the deal to remain in effect, Bug would have to officially extend its option to continue.

But after Mars told Bug that he wanted out, Bug “shifted gears, and suddenly argued that (Mars) had not, in fact, met the minimum release requirements,” Niborski wrote. The Bug Music website continues to list Mars as a client.
