Reason for Kim's Lookalike Lawsuit? Sears Deal

OK, so maybe it wasn't jealousy that led Kim Kardashian to sue Old Navy for using her doppelganger in commercials. Sources tell TMZ she actually filed the suit in order to protect a deal her family has with Sears to sell the Kardashian Kollection, a clothing and bedding line launching in a month and a half. Sears executives supposedly thought Kim may have even been involved in the Old Navy ads, and feel that the lookalike campaign will harm its own campaign for the Kardashian Kollection. Need more Kim?
