Teen singer/actress Lindsay Lohan's mother is being sued for fraud over her superstar daughter's music deal. Music producers ANTONIO ALMEIDA and MITCHELL CHAIT allege they signed a three-way partnership deal with Dina Lohan involving the MEAN GIRLS star's music career in 2002. Las Vegas, Nevada, newspaper the Review Journal reports Almeida and Chait have filed suit against Dina, claiming they recorded half an album with Lindsay alongside Emilio Estefan in 2002 and 2003. In 2004, Dina went on to sign a deal with Tommy Mottola's Casablanca Records, which produced Lindsay's two albums SPEAK and A LITTLE MORE PERSONAL (RAW). Almeida and Chait allege they leant Dina tens of thousands of dollars for Lindsay's music.
