Mischa Barton Loves t.A.T.u.

Remember t.A.T.u. - that catchy Russian girl group where the two singers dressed like schoolgirls and made out? And then they wound up being fake lesbians who exploited the girl-on-girl thing just for publicity? And then they disappeared?

Get ready for the t.A.T.u. revival, as O.C. star Mischa Barton will star in Finding t.A.T.u., a drama about a young American woman in Russia who bonds with a female local over their mutual love of the musical duo.

The book on which the film is based features a lesbian affair between the two lead characters, but director Roland Joffe (The Killing Fields, Captivity) is keeping mum over whether or not Mischa will get her lady-lovin' on in the movie version.

Perhaps more nuggets will surface when shooting begins this month.
