Beyonce is filming an alternate version of her 'Best Thing I Never Had' music video and wants your help to make it happen.

Queen B is a blushing bride in the wedding day-themed original video for her second '4' single, which is set to get a matrimonial makeover by way of fan submissions. Beyonce wants real photos and video footage from her fans' own wedding days.

The original video also includes a fictional flashback of Bey with her deadbeat boyfriend at prom, so fans' prom footage is also welcome -- if you are so brave.

Fans can upload their wedding or prom video footage to YouTube and their photos to Flickr with the tag #BeyonceBestThing, through the August 12 deadline.

The chosen submissions will appear on BeyonceOnline and Celebuzz and, of course, the upcoming 'Best Thing I Never Had' fan video!

Beyonce's plans for a 'Best Thing I Never Had' alternate video follow the recent surfacing of a smoking hot alternate version of her 'Run the World (Girls)' video.
