The Queen of Pop is gearing up to direct her second film – this time about the woman who never would be queen – Wallis Simpson, the Duchess of Windsor.

"It's still in the early stages," Madonna's publicist, Liz Rosenberg tells PEOPLE about the movie, which will chronicle how King Edward VIII turned in his crown in 1936 to marry the twice-married American socialite.

The screenplay, which Madonna, 51, wrote, "is about two intermingling love stories – one with the Duke and Duchess of Windsor and the other one a modern day love story," says Rosenberg.

Reports that it will be a musical like Madonna's 1996 film, Evita aren’t completely true, says Rosenberg. "It's not a musical but will likely have a musical component,” she says.

Madonna, who made her directorial debut in 2008 with Filth and Wisdom, is excited about bringing one of the greatest love stories to the silver screen, says Rosenberg. "She did a lot of research on the Duke and Duchess of Windsor," she says.
