Lindsay Lohan wants to open her own boutique -- selling something she knows a little about -- jewelry and fashion!

The Mean Girls star, 24, is making plans to open two stores, one in Venice, California, and Soho, New York, in partnership with mother Dina, Breaking Celebrity News has exclusively learned.

"Both Dina and Lindsay love the fashion industry and are excited to do this together," a close family friend told Radaronline.com.

The mother-daughter fashionistas have plans to sell both clothing and jewelry, we're told, while the rehabbed starlet splits her time between both coasts.

"Right now, Lindsay loves being in Venice in her new home and enjoys the walk into town," said the source.

As Breaking Celebrity News reported, Lohan entered a plea of not guilty to a felony grand theft charge at the Airport Courthouse in Los Angeles on Wednesday, before Superior Court Judge Keith L. Schwartz.
