Christina Aguilera is preparing to hit a big (key)note…

The 31-year-old half-Ecuadorian American singer and The Voice coach will serve as a keynote speaker at the 2012 Billboard and Hollywood Reporter Film & TV Music Conference.

The five-time Grammy Award winner, one of the top-selling artists of all-time, is in a unique position to discuss the connection between film, TV, and music. Her career started on television with The Mickey Mouse Club, and today she’s watched by millions each week as a coach on NBC‘s The Voice.

Taking place at the W Hotel in Hollywood October 24 and 25, the Q&A session will feature Aguilera discussing her musical journey, her upcoming album, and the role television has played and continues to play in her life and career.

Besides Aguilera, Epic Records chairman and The X Factor judge Antonio “L.A.” Reid and composer Gustavo Santaolalla will deliver the two other keynote Q&As at the two-day conference.

“Music has always played an integral part in film and television and now with the ever-growing popularity of music competition shows, new doors are being opened for some of the biggest players in the industry” said Bill Werde, Billboard’s editorial director. “Both Christina Aguilera and L.A. Reid’s music careers have given them entrée into television, and we are thrilled to have them share their stories and perspectives on the impact of music.”

Now in its 11th year, the conference offers attendees a unique opportunity to learn from, network and expose their music directly to the industry’s most influential executive and creative talents including award-winning composers and directors, key studio, network, record label and publishing professionals, VIPs from the advertising, gaming and commercial fields as well as the best music supervisors in the business.
