The former In Living Color stars have been following the rise of Sotomayor's career since before she was nominated for the Supreme Court by President Barack Obama earlier this year (09).

According to reports, they are both keen to make a biopic - and the race is on to see who can secure the film rights first.

A source tells the National Enquirer, "Rosie resents Jennifer going after the project because she says she would have wanted to make the movie whether Sotomayor was confirmed or not.

"(Lopez) hosted a dinner party for Justice Sotomayor right after her confirmation. It was to butter her up because Lopez thinks a film about her life story would be huge.

"Considering this is Hollywood... there may be two film versions of Sonia Sotomayor's life."

Puerto Rican actresses Jennifer Lopez and Rosie Perez are battling over the rights to turn the life story of Sonia Sotomayor, the first Latina appointed to the U.S. Supreme Court, into a movie.
