Romantic comedy heaven is made when a 'Twilight' hunk and a pop star are cast as love interests. That is just the case in 'Love, Wedding, Marriage,' starring Kellan Lutz and Mandy Moore as newlyweds, according to The Hollywood Reporter.

For the film, Mandy has vowed to play a marriage counselor who is crushed with news that her parents' seemingly perfect marriage is ending in divorce. Determined to rectify their issues, she puts her own relationship in jeopardy. James Brolin and Jane Seymour have been tapped to play the parents in the failing matrimony.

Actor Dermot Mulroney will be calling the shots in his directorial debut, reports The Hollywood Reporter. Though the movie may take on a different name, 'Keep It Together,' it has sent out save the date cards for April 19 to begin filming in Louisiana.

In real life, Mandy is a newlywed, marrying Ryan Adams in March 2009.
