Britney's Lawsuit-a-palooza

Britney Spears hasn't released a new song for a couple of months, but that's not keeping the pop tart from being in heavy rotation--at least among the legal set.

The songwriters behind Spears' 2005 opus "Do Somethin'" have filed suit against a South Korean pop composer, alleging he ripped them off.

Universal Music Publishing Korea, the company that handles overseas rights to Mrs. Federline's musical gems, says that the team behind "Do Somethin'" (the track is credited to frequent Spears collaborators C. Karlsson, P. Winnberg and H. Jonback, along with A. Hunte) believes the tune was "partially plagiarized" by a single called "Get Ya" from the popular South Korean singer Lee Hyo-lee.

Spears released her ditty in November 2004 as one of the few new tracks to appear on her Greatest Hits: My Prerogative album; it was released as a single in February 2005 and peaked at 100 on the Billboard Hot 100 singles chart. "Get Ya," the first single off Lee's second album, was released just last month.

The legal action targets "Get Ya" songwriter Kim Do-hyun. Kim reportedly has admitted being influenced by the Britney song, but has denied the allegations that he copied directly from it.

Spears wasn't directly named as a plaintiff in the suit, although it makes frequent reference to her.

Likewise, the "Toxic" singer isn't named as a defendant in a lawsuit filed Tuesday by three former employees, but a trio of her companies are.

Lonnie D. Jones and Randy Jones, identified in the suit as former security guards, and Silas Dukes, described as a "lead specialist" in the court filing, allege they weren't paid for overtime and never received their final paychecks after being fired last November.

They are seeking back wages and unspecified penalties for alleged labor-law violations from the Louisiana-based Britney Brands. The other defendants are Britney Touring and Team Tours.

According to the suit filed in Los Angeles Superior Court, the three men claim Spears required them to work a minimum of 12-hour days and take trips with her that demanded they be on call 24 hours a day, often without meal or rest breaks.

There was no comment from the Spears camp Wednesday on either of the Brit-centric legal actions.
