'Step Brothers' Catalina Wine Mixer Happening Again This Year

Exclusive Details

The real-life Catalina Wine Mixer is no longer just that legendary scene from "Step Brothers" -- it's now well on its way to becoming a full-blown festival ... thanks to a rocking lineup for 2016.

Last year's inaugural event was so successful promoters are making this year's a 3-day event, and we've learned the headliner's gonna be alt-rockers Kongos, best known for "Come With Me Now."

They're keeping up one important tradition -- The Dan Band will close the SoCal island mixer, slated for Sept. 23-25.

Attendees are encouraged to dress up like stars from the movie on day 1, and best dressed scores a free trip back to Catalina.
