Christina Aguilera

Christina María Aguilera (born December 18, 1980) is an American singer-songwriter and actress. In the early 1990s, she appeared on television series Star Search and The Mickey Mouse Club. In 1998, Aguilera signed with RCA Records and recorded her self-titled debut album, which was released in 1999. The album was a commercial success in the United States, spawning three U.S. Billboard Hot 100 number-one singles—"Genie in a Bottle", "What a Girl Wants", and "Come On Over Baby (All I Want Is You)", and helped Aguilera win the Grammy Award for Best New Artist. In 2000, RCA released Aguilera's Spanish-language album Mi Reflejo and holiday-theme album My Kind of Christmas. Her 2002 fourth studio album, Stripped, ventured into various genres including hip hop, Latin, and rock, and won a Grammy Award for Best Female Pop Vocal Performance for its second single "Beautiful".

Aguilera's 2006 fifth studio album, Back to Basics, was inspired by blues, soul, and jazz music of the 1920s-40s. The album peaked at number one on record charts of thirteen countries and won a Grammy Award for Best Female Pop Vocal Performance for its first single "Ain't No Other Man". In 2010, RCA released Aguilera's electronic-influenced album, Bionic, which failed to match the success of her previous albums; later that year, she starred in the film Burlesque. The following year, Aguilera was featured on Maroon 5's top-ten single "Moves like Jagger" and became an original coach on the U.S. television series The Voice, having since appeared on five of its nine seasons. Her 2012 seventh studio album, Lotus, became the lowest-selling album of her career. However, she later experienced rehabilitated commercial success in 2013, being featured on the top-ten singles "Feel This Moment" and "Say Something", which won a Grammy Award for Best Pop Duo/Group Performance.

Ariana Grande

Ariana Grande-Butera (born June 26, 1993), known professionally as Ariana Grande (/ˌɑːriːˈɑːnə ˈɡrɑːndeɪ/), is an American singer and actress. She began her career in the Broadway musical 13, before landing the role of Cat Valentine on the Nickelodeon television series Victorious in 2009. After four seasons, the show ended, and Grande starred on the spinoff, Sam & Cat, which ended in 2014. She has also appeared in other theatre, television and film roles and lent her voice to animated television and films.

Grande's music career began with the soundtrack Music from Victorious (2011). She signed a recording contract with Republic Records and released her debut studio album Yours Truly in 2013, which debuted at number one on the US Billboard 200. The album's lead single, "The Way", reached the top-ten of the Billboard Hot 100, with critics comparing her wide vocal range to Mariah Carey's.

Grande's second studio album, My Everything (2014), also reached number one in the United States and charted well in various other countries. With the singles "Problem", "Break Free", "Bang Bang" and "Love Me Harder" from that album, she spent 34 continuous weeks in the top 10 of the Billboard Hot 100 and had the most top 10 singles of any artist in 2014. In 2015, Grande promoted My Everything with her first world tour, The Honeymoon Tour, and guest-starred in the Fox comedy-horror TV series Scream Queens. She also released the lead single "Focus" from her upcoming third album, released a holiday EP album, Christmas & Chill, and was heard on several collaborative projects.
