The Liz and Dick actress - who launched the 6126 Collection along with her business partner Kristi Kaylor in 2008 - is expected to file a $1.1 million lawsuit against the label today over rights to the 6126 brand name, reports TMZ.
The troubled star, 26, claims she owns the trademark to 6126.
Miss Lohan's lawyer, Perry Wander, is expected to file the lawsuit in federal court today.
Her 6126 line - which has been inactive since 2010 - specialized in leggings designed by the actress before ranging into a wide variety of clothing.
