LOS ANGELES - Salma Hayek will star in and produce an untitled romantic comedy for Walt Disney Pictures.

The story follows a conservative doctor who gets the surprise of his life when he learns that the ex-boyfriend of his fiancee (Hayek) is an international Latin superstar who has come to Los Angeles to win her back.

The script was written by Ed Decter and John Strauss, whose credits include Disney's last two "Santa Clause" movies.

Hayek is doing voice work on Disney's "South of the Border." She also is an executive producer of Disney-owned ABC's "Ugly Betty," which is up for 11 Emmys, including one for Hayek for guest actress in a comedy series.
