Joe Jonas is set for an embarrassing on-set encounter with his ex-girlfriend Taylor Swift after signing on to join the cast of her star-studded new movie Valentine's Day.

The Jonas Brothers star is reportedly in talks to join Swift, Julia Roberts, Anne Hathaway and Jessicas Biel and Alba in Garry Marshall's new movie. Jonas famously dumped the Love Story singer by phone and she went on talk show Oprah to tell the world.

The Love Bug singer is expected to play himself in the film, according to Eonline.com, while Swift will have a leading role and is in talks to record the movie's soundtrack.
