From 'Dirrty' to XTina: Christina Aguilera's dramatic transformation over the years

Christina Aguilera has faced criticism over her body image throughout her career, but she has never backed down from her evolving physical look, not even when she was accused of being 'on both sides of the scale.' The 43-year-old singer recently revealed her weight loss while putting on an amazing act for the inaugural show of her Las Vegas residency. After years of ups and downs, she is finally 'having a booty' and keeping an attractive and strong figure.

Christina Aguilera debuted with the '90s song 'Genie in a Bottle'

According to a 1999 story by Rolling Stone, Christina Aguilera first gained popularity among youths in the '90s when her music video for 'Genie in a Bottle' debuted on MTV and reached No 1 on 'Total Request Live' in July 1999. Aguilera made her legendary MTV debut a few months after her former 'Mickey Mouse Club' co-star Britney Spears released 'Baby, One More Time'.

Christina Aguilera's 2001 rendition of 'Lady Marmalade' on the 'Moulin Rouge' soundtrack, featuring Missy Elliott, Pink, and Lil' Kim, was probably the first hint that she was shaking things up. Christina began a new chapter in her life with the release of 'Dirrty' in 2002. The Grammy Award-winning singer showcased her persona, 'Xtina,' who didn't hesitate to flaunt multiple piercings, two-tone hair, and skimpy clothing.

Christina Aguilera's first marriage in 2005

Along with changing her image with the release of the edgy album 'Stripped' in 2002, Christina Aguilera also met the man she would eventually marry. She married Jordan Bratman, a music executive for her management business, in a magnificent wedding at a Napa Valley, California, winery in November 2005, per People. Aguilera gave birth to the couple's first child, Max Liron, on January 12, 2008.

Divorce in 2011

Christina Aguilera's marriage to Jordan Bratman ended after just five years. The marriage came when she was 24, and it seemed she was still developing into the person she would become. Then there was the adultery, from both sides. In an interview with W Magazine, the singer acknowledged that she and her ex-husband were "not angels."

Engagement to Matthew Rutler in 2014

Christina Aguilera, who starred in the 2010 film 'Burlesque', spoke about her "self-discovery" process to W Magazine. It was also at this time that Aguilera fell in love with her fiance, Matthew Rutler, a production assistant on the movie. Aguilera confirmed her engagement to Rutler in February 2014, and by August of the same year, she gave birth to her second child—a girl named Summer Rain—with Rutler.

Christina Aguilera exited 'The Voice' in 2016

Christina Aguilera joined fellow judges Adam Levine, Blake Shelton, and CeeLo Green in the coach's chair for the NBC premiere of 'The Voice' in April 2011. After serving as a coach for six seasons, Aguilera decided to leave the show, per Billboard. She told People at the time that although she claimed the show gave her children security and "a more grounded position," she acknowledged that eventually it "wasn't the right fit" for her.

Las Vegas residency The Xperience launched in 2020

Christina Aguilera launched her Las Vegas residency, 'The Xperience,' a year after leaving NBC, where she performed until March 2020.

Aguilera revealed to Health in 2021 that she "hated being super skinny" when she was younger but now enjoys her curves.

She follows a plant-based diet plan and eats colorful fruits and vegetables every day. She told L'Officiel Italia in 2020 that she had given up on dieting and was instead concentrating on eating healthy.
