Christina Aguilera kicked off her highly-anticipated residency, The Xperience, at Planet Hollywood's Zappos Theater this past weekend. The pop queen takes fans, whom she calls "Fighters" on an incredible musical journey made up of six acts that celebrate her biggest hits, along with her deep cuts and covers.

Aguilera opened with the never-before-performed-live hit "Your Body." The crowd went wild when she appeared on stage in a white geometric bodysuit and matching halo. She then launched into her 2010 hit "Not Myself Tonight," followed by a remix of "Genie in a Bottle."

She continued to take audiences down memory lane with her performance of "Reflection," which Aguilera sang for the soundtrack of Disney's animated film, Mulan.

“This song has always been such a gigantic part of my history and my life, going from Mickey Mouse Club to the Mulan soundtrack, that's what really kicked it off,” Aguilera said. “This aligns with the message of tonight. We all wear a mask in some way -- for our kids, for our jobs, for our families, for other people in general. When we go home, we get to take that mask off and look in the mirror and be who we really need to be at the end of a long day. Tonight, I encourage you to take off your mask or put one on, feel free.”

Aguilera stunned when she sang Whitney Houston's "I Love the Lord." She said it was the song she auditioned with to get her record deal.

The rest of her set included renditions of "What a Girl Wants," "Come on Over (All I Want Is You)," "Ain't No Other Man," "Beautiful," "Fighter" and "Candyman."

She ended The Xperience with an encore performance of her dance-pop hymn "Let There Be Love," which she dedicated to the LGBTQ community.

The show will continue through June and will also feature September dates.
