New Line has assembled a star-studded cast for its latest romantic comedy, Valentine's Day, so far including Julia Roberts, Anne Hathaway, Jessica Alba, Jessica Biel, Jennifer Garner, Shirley MacLaine, Bradley Cooper and Ashton Kutcher in final negotiations to star.

According to The Hollywood Reporter, Garry Marshall will direct the film, which has five slightly interconnecting stories playing out during a Valentine's Day in Los Angeles.

Roberts is an army officer on leave from Iraq on a flight to L.A. Cooper, on the same flight, is a gay man whose lover is a closeted football player.

Kutcher is an owner of a flower shop who proposes to his girlfriend (Alba), only to realize he is in love with his close friend, played by Garner, who discovers her boyfriend is married.

MacLaine plays Roberts' mother, a happy retiree who reveals to her husband a long-ago affair.

Hathaway is an assistant working at the biggest talent agency in town and dating a mailroom assistant; Biel is a publicist unlucky in love (is there any other kind?) who has no date on Valentine's Day.

Major roles still to be cast are the gay football player, MacLaine's husband, the mailroom worker, a talent agent and a young boy looking to give his crush some flowers.

Katherine Fugate wrote the initial draft, while Abby Kohn and Marc Silverstein penned the latest.

No production date has been set.

Valentine's Day was released February 12th, 2010 and stars Jessica Alba, Kathy Bates, Jessica Biel, Bradley Cooper, Eric Dane, Patrick Dempsey, Hector Elizondo, Jamie Foxx. The film is directed by Garry Marshall.
