LOS ANGELES– Are Steve Carell and Tina Fey teaming up once again?

The duo, who will be seen opposite each other next April in "Date Night," are loosely attached to star in "Mail-Order Groom," a Warner Bros. comedy about a naive single woman who can't find love and ends up with a husband from eastern Europe, bringing him home to the States.

The story is based on an idea by Fey's husband, composer Jeff Richmond, along with Robert Carlock ("30 Rock") and Scott Silveri ("Friends") who wrote the original script.

The onscreen reunion for the duo, however, is a dicey proposition. The project has no director, and the only window for Carell and Fey to shoot would be the hiatuses of their respective TV shows, "The Office" and "30 Rock." Fey doesn't wrap "Rock" until March 23, then goes into PR mode during the month of April for Fox's "Date Night."
