Grapevine on Feb. 28th

Jonas Brothers to appear in Grapevine

To thank their fans in person (read: to promote the opening of their film), Westlake's most famous singing siblings will hopscotch around the country this weekend for surprise visits to theaters showing Jonas Brothers: The 3D Concert Experience.

The secret's out in North Texas, though: Publicists announced that Grapevine will be one of the stops for Joe, Nick and Kevin. The brothers will walk the red carpet Saturday night (estimated time: 10:30 p.m.) at Main Event Entertainment, 407 W. State Highway 114, after a private screening of the film.

Fans won't be able to attend the screening, but they're encouraged to come for the red-carpet arrivals. Producer Timbaland also will make an appearance.
