Justin Randall Timberlake (born January 31, 1981) is an American singer, actor, and businessman. He achieved early fame when he appeared as a contestant on Star Search, and went on to star in the Disney Channel television series The New Mickey Mouse Club, where he met future bandmate JC Chasez. Timberlake became famous in the late 1990s as the lead singer and youngest member of the boy band 'N Sync, whose launch was financed by Lou Pearlman.

In 2002, he released his debut solo album, Justified, which sold more than seven million copies worldwide. The album was a commercial success, spawning the hits "Cry Me a River" and "Rock Your Body". Timberlake continued his success with his second solo album, FutureSex/LoveSounds (2006), debuting at number one on the Billboard 200 chart, and produced the US number-one hit singles "SexyBack", "My Love", and "What Goes Around... Comes Around".

Timberlake has won six Grammy Awards and four Emmy Awards. His first two albums made him one of the most commercially successful singers in the world, each selling in excess of 7 million copies. He also has an acting career, having starred in films such as The Social Network, Bad Teacher and Friends with Benefits. His other ventures include record label Tennman Records, fashion label William Rast, and the restaurants Destino and Southern Hospitality.

Hayley Nichole Williams (born December 27, 1988) is an American singer and songwriter. She is the lead vocalist of the American rock band Paramore.

In 2002, at the age of 13, Williams moved from her hometown, Meridian, Mississippi, to Franklin, Tennessee. She met band members Josh and Zac Farro in her new school. While still in school, she tried out for a local funk cover band The Factory, in which she met Jeremy Davis.

Williams was discovered in 2003 by managers Dave Steunebrink and Richard Williams who signed the 14-year-old to a production deal. At the time she was writing pop songs with songwriters in Nashville. Williams was introduced to Atlantic Records A&R Tom Storms through Richard Williams' attorneys Jim Zumwalt and Kent Marcus, and then signed to the label by Jason Flom. The label's original plan for their new artist was to make her a solo pop artist but Williams objected to this, saying that she wanted to be part of a band and play alternative rock music.

Atlantic decided to go along with her wishes, and she then formed Paramore with Josh Farro, Zac Farro, and Jeremy Davis. The music of Paramore was originally supposed to come out on Atlantic Records, but the label's marketing department decided it would be better for the image of the band to not have them attached to a huge label. They instead released their music through a "cooler" niche label, Fueled by Ramen. The debut album was released in 2005 when Hayley was only 16 years old.
