Zachary David Alexander "Zac" Efron (born October 18, 1987) is an American actor and singer. He began acting professionally in the early 2000s and became known with his lead roles in the Disney Channel Original Movie High School Musical, the WB series Summerland, and the 2007 film version of the Broadway musical Hairspray. Efron has since starred in the films 17 Again, Me and Orson Welles, Charlie St. Cloud, New Year's Eve, and The Lucky One.
In 2007, Rolling Stone declared him the "poster boy for tweenyboppers" and featured him in their late August 2007 issue.
Efron was born in San Luis Obispo, California, and later moved to Arroyo Grande, California. His father, David Efron, is an electrical engineer at a power station, and his mother, Starla Baskett, is a former secretary who worked at the same power plant. Efron has a younger brother, Dylan, and had, as he has described it, a "normal childhood" in a middle class family. He is an agnostic, having never been religious. His surname, "Efron", means "lark" in Hebrew (his paternal grandfather was Jewish).
Christina María Aguilera (born December 18, 1980) is an American recording artist and actress. Aguilera first appeared on national television in 1990 as a contestant on the Star Search program, and went on to star in Disney Channel's television series The Mickey Mouse Club from 1993 to 1994. Aguilera signed to RCA Records after recording "Reflection", the theme song for the animated film Mulan (1998).
In 1999, Aguilera came to prominence following her debut album Christina Aguilera, which was a commercial success spawning three number one singles on the Billboard Hot 100—"Genie in a Bottle", "What a Girl Wants", and "Come On Over Baby (All I Want Is You)." Her sophomore and her debut Latin-pop album, Mi Reflejo (2000), a Christmas third studio album, My Kind of Christmas (2000), and several collaborations followed which garnered Aguilera worldwide success, though she was displeased with her lack of input in her music and image. After parting from her management, Aguilera took creative control over her fourth studio album, Stripped (2002). The album's second single, "Beautiful", was a commercial success and helped the album's commercial performance amidst controversy over Aguilera's image. Aguilera followed up Stripped with the soul, jazz and blues inspired, Back to Basics (2006), released to positive critical acclaim. The album produced three singles "Ain't No Other Man", "Hurt" and "Candyman". Four years later Aguilera released her sixth studio album, Bionic (2010), which incorporated aspects of R&B, electropop, and synthpop and was met with mixed reviews and low sales. Aguilera's seventh studio album is set to be released in 2012.
