You can’t discuss ’00s pop icons without bringing up Christina Aguilera.
At just 18 years old, the powerhouse singer made her debut in 1999 with her self-titled album and it didn’t take long before the record became an instant classic. With songs such as “Genie in a Bottle,” ‘What A Girl Wants,” “So Emotional” and “I Turn to You,” Christina Aguilera received major acclaim from fans and critics.
In the following years the former Disney Mouseketeer churned out hit after hit — Dirrty, Lady Marmalade, Ain’t No Other Man, Candyman, Hurt – and solidified her place as pop culture royalty.
Just recently, Aguilera celebrated the 25th anniversary of her debut album and tapped modern-day pop stars such as Sabrina Carpenter and Machine Gun Kelly to mark the milestone anniversary.
As we continue to celebrate and replay one of the most essential albums of the early aughts, look back at Christina Aguilera’s style evolution.
