Fans of The Bold and the Beautiful are enjoying a unique, interactive opportunity:

Viewers of the soap opera are invited to participate in the outcome of the on-air “Boldface Challenge.” To do so, simply by log into the official website at Bold Face Records to vote for your favorite duet sang by either Constantine and Phoebe (Constantine Maroulis and Mackenzie Mauzy) or Rick and Phoebe, (Kyle Lowder and Mackenzie Mauzy).

Each vote is also an entry into a contest in which the Grand Prize Winner will receive a trip for two to the set of The Bold and the Beautiful in Los Angeles.

Other prizes include T-shirts, Boldface Records hats, and Constantine Maroulis’s new CD. Pretty cool stuff overall.

The contest runs August 1st through August 19. The Grand Prize winner will be announced on August 24, while the winning singing duo will be announced August 27.
