Multi-platinum, Grammy Award-winning worldwide pop icon Britney Spears and singer, songwriter and actress Demi Lovato will join L.A. Reid and Simon Cowell as judges on “The X Factor,” the hit singing competition series returning this fall on FOX.

Spears is one of the most successful and celebrated entertainers in pop history. Her musical career boasts nearly 100 million albums sold worldwide and countless awards and accolades, including the 2011 MTV Video Vanguard Award and Billboard’s Best-Selling Female Artist of the Decade (1998-2008). Spears first captivated audiences with her first single “…Baby One More Time,” an international hit that is currently 14x Platinum in the U.S. So far, Spears has earned a total of five No. 1 debut albums and 24 Top 40 songs in her career.

Lovato is an accomplished singer and actress with a devoted and engaged young fan base. Her single, “Skyscraper,” off of her most recent album, “Unbroken,” recently went platinum, while the video for her new single, “Give Your Heart a Break,” already has garnered 10 million YouTube views. Her first album, “Don't Forget,” debuted at No. 2 on the Billboard 200 chart and her second album, “Here We Go Again,” debuted at No. 1. Lovato began acting at the age of 10 and starred in the cable television series, “Sonny With A Chance.” Her film credits include “Camp Rock” and “Princess Protection Program.”

"I'm absolutely delighted Britney and Demi are joining us,” said Simon Cowell. “Britney remains one of the biggest stars in the world, she's talented, fascinating and I believe she knows exactly how to spot the X factor. Demi's had an amazing career in music, TV and film for someone her age. She's young, confident and enthusiastic. I think it’s really important that she speaks to our younger audience. The new panel will be dynamic and will work really well with the changes we are making to the show.”

Spears added, “I couldn't be more excited to join “The X Factor” judging panel. I'm a huge fan of the show and now I get to be a part of the action. Simon and L.A. better watch out!”

“I'm so thrilled to join this legendary group of judges on “The X Factor,” said Lovato. “To be able to spend each week with Simon, L.A. and Britney watching the best that America has to offer is truly a dream come true.”

Mike Darnell, president of Alternative Entertainment, Fox Broadcasting Company, noted, “Britney is an unparalleled superstar. Her success in the music industry over the last two decades makes her a perfect fit for “The X Factor” judging panel. Demi has mass appeal and is beloved by her fans around the world. We are incredibly lucky to have them on board and we know they will bring so much excitement to the judging table for Season Two.”

In its first season on FOX, “The X Factor” shot to the top of the ratings as the No. 1 unscripted series of the fall and currently ranks as a Top 10 series among Adults 18-49 and the No. 1 new series among Women 18-49.

“The X Factor” is searching for undiscovered talent 12 years old or over – both solo artists and vocal groups – who are willing to brave the panel for a chance to win a $5 million recording contract with Syco/Sony Music.

In a departure from other singing competition series, the first time contestants audition for “The X Factor” judges, they will do so in front of an audience of thousands – raising the stakes and increasing the pressure to impress not only the judges, but also a potential legion of fans. This will be the ultimate test to prove they have the vocal ability, charisma and stage presence that it takes to win an unprecedented $5 million recording contract with Syco/Sony Music.

The shows are at the Dunkin’ Donuts Center three days only, June 27-29. Tickets are free. Join the judges in the TV studio audience as the best singers in the country perform live. For more information and to print free tickets visit www.TheXFactorTickets.com.
