Bow Wow -- Another Day, Another Lawsuit

Bow Wow's 2012 is off to a rather litigious start -- not only is he buried in tax liens, and a wanted man in Georgia for ducking a civil lawsuit ... but now he's being sued by a limousine company, just for good measure.

According to a lawsuit filed this week in Georgia, Bow Wow (real name Shad Moss) stiffed the limo company to the tune of $3,594.87.

Our sources say the bill goes all the way back to 2008 and stems from services provided in California.
