Christina Aguilera has changed her image once again.

The Grammy Award winner has ventured into a new branch of music where very few artists have actually succeeded.

A lot has changed for the 29-year-old since the release of her last album “Back To Basics,” the jazz and blues-infused album that solidified her as one of music’s top contenders.Since 2006, Aguilera married, had a baby and starred in her first film role, “Burlesque,” co-starring Cher and Stanley Tucci.

The Pennsylvania native has created a name and an image for herself. Starting as a Mousequeteer at the Mickey Mouse Club and leading to her debut single “Genie In A Bottle” in 1999, Aguilera took no time in becoming a household name.

In 2002 she broke all molds of pop conventionalism with the release of her much-anticipated sophomore effort “Stripped,” an album which found her all grown up, much more mature and ready to call the shots in her own life. She wrote and produced most of the album, making it incredibly personal and tremendously controversial.

In late 2008, she released her first greatest hits collection, “Keeps Gettin’ Better: A Decade Of Hits,” which featured two new tracks “Dynamite” and “Keeps Gettin’ Better.” The new tracks promised a snippet of what was to come.

Two years later, the promise has been delivered. Aguilera is not the same girl she was in her “Back To Basics” days.

Now four years after the release of the album, she has come back with a distinctive sound.The new album is called “Bionic,” and it hits stores June 8. The first single “Not Myself Tonight” debuted on her official Web site March 30 and hit the airwaves April 5.

Aguilera broke her silence with the pulsating three-minute track, revealing a side most of the world hadn’t seen since her “Dirrty” days. The song makes the claim that the singer has found in herself a brand new woman.

At first the song sounds like any other electronic infused pop track, but once her powerful voice breaks through the synthesizers, all bets are off.  She manages to bring the song to life in a way that none of her contemporaries could do.

For the upcoming album, Aguilera has worked with Australian singer Sia, electropop band Ladytron and critically acclaimed English singer/songwriter M.I.A. With so many talented hands in this project, “Bionic” will prove to be a force to be reckoned with.

On Jan. 22, Aguilera performed the song “Lift Me Up” for the “Hope for Haiti Now: A Global Benefit for Earthquake Relief” telethon. The soaring ballad was crafted with the help of long-time collaborator Linda Perry and will be featured in the upcoming album.

“Not Myself Tonight” went on sale April 13 on iTunes.
