Christina Aguilera is widely recognized as one of the most talented vocalists of her time. With the ability to hit huge notes that are capable of filling an entire arena while simultaneously being able to nail glass-shattering falsetto pitches, Ms. Aguilera never ceases to amaze with her otherworldly voice. In honor of the songstress, we want to know: Which Christina Aguilera album gets your vote for the "best"?

In 1999, the world was introduced to Christina Aguilera the solo artist (not the Mouseketeer) with her debut, self-titled album and the LP made her the superstar she is today. It reached No. 1 on the Billboard 200 and boasts chart-topping singles like 'Genie in a Bottle,' 'What a Girl Wants' and 'Come on Over Baby.' A year later, Aguilera channeled her Ecuadorian roots and released the Spanish-sung album 'Mi Reflejo,' which won a Latin Grammy for Best Pop Vocal Album in 2001.

In 2002, Aguilera introduced her raunchy alter ego Xtina with her album 'Stripped.' The singer exhibited a lot of growth with this release, ditching her teen idol exterior with deeper tracks like 'Beautiful,' more edgy songs like 'Fighter' and sexy singles like 'Dirrty.' Not too long after, Aguilera dropped 'Back to Basics,' and she transformed herself once again into a retro-glam diva with funky singles like 'Ain't No Other Man' and the swing-inspired number 'Candy Man.'

Finally, in 2010, Christina Aguilera unleashed her most current album to date, 'Bionic.' Although she was met with a lot criticism and poor reviews for this album, it was still a massive hit amongst her fans thanks to catchy, futuristic songs like the title track and seductive, sexually-charged singles like 'Not Myself Tonight' and 'Woohoo,' which features Young Money rapstress Nicki Minaj.

So, Christina fans, which one of Aguilera's albums (not counting her Christmas album!) do you think is best body of work to date? Cast your vote below!
