Date Of Birth

April 10, 1991


Amanda Joy “AJ” Michalka was born April 10, 1991 in Torrance, California. Michalka was raised in Seattle, along with sister Alyson (“Aly”) and from an early age showed an interest in music and acting. The sisters got their start singing in church and acting in school plays. AJ quickly followed suit when Aly began studying acting and working as a print model, and soon the sisters were performing as the duo Aly & AJ.

AJ, like her sister, is an accomplished musician, singer, and songwriter. The girls write their own music, and AJ plays many instruments, including guitar, piano, and bongo drums. The girls penned all the songs on their debut album, Into the Rush (2006). Aly & AJ also released a Christmas album, Acoustic Hearts of Winter, in 2006, and followed up with their sophomore album, Insomniatic, in 2007.

AJ has made cameos and multiple-episode appearances on several acclaimed and prime time television series, including The Guardian, Oliver Beene, Six Feet Under, and General Hospital.

AJ wrote the song “My Way,” which Alyson sung in one episode for her role as Keely Teslow on the Disney Channel’s Phil of the Future. The duo’s music has also been featured in several films. Aly starred in Disney’s Now You See It (2005), which included the girls’ cover of The Loving Spoonful’s “Do You Believe in Magic?” Original songs “No One” and “Greatest Time of Year” appeared in Disney’s Ice Princess and Santa Clause 3: The Escape Clause, respectively.

Aly has kept busy with both music and acting projects. In 2006 the sisters starred in Cow Belles as sisters Taylor and Courtney Callum, two farmers’ daughters with a plot to save the family dairy farm. Aly and AJ also landed starring roles in MTV’s movie version of My Super Sweet Sixteen, playing rival teen queens in an intense birthday blowout war. The movie premiered on July 8, 2007, and MTV released the DVD for the film July 10, the same day that the girls released Insomniatic.
