Just like "American Idol," the hit U.K. talent show "The X Factor" knows how to pull out all the stops for the finale. During a news conference Thursday (November 9), the finalists revealed a star-studded lineup of collaborations, including Christina Aguilera, Rihanna, Robbie Williams and will.i.am., for the final show of the season on Saturday.
"We will be duetting with Robbie Williams," judge Simon Cowell said on behalf of his five-member boy band One Direction.
Asked how they felt about working with the British singer, one member was especially eager to collaborate with such a high-profile artist. "I'm a massive fan of Robbie," Louis Tomlinson said. "In the U.K., he's absolutely massive, and it's an honor for us to get a chance to perform with him."
Another music sensation fans can expect to see grace the "X Factor" stage is Christina Aguilera. "I'm duetting with Christina Aguilera, and I'm very happy," Rebecca Ferguson revealed. "She's very talented and amazing."
Cher Lloyd announced that she'll team up with Black Eyed Peas frontman will.i.am for her performance. Lloyd's mentor, British pop sensation Cheryl Cole, has worked with Will in the past and was excited for Cher. "I just told her she's in a very, very fortunate position," Cole said. "He's the biggest superstar in the world. She knows how lucky she is. She's excited. It's right up her street."
Rihanna will bring her Caribbean flavor to a performance alongside Matt Cardle. "I'm going to sing the best I can this weekend and perform the best I can," the contestant said.
