Christina Aguilera – Age 40
Many things have changed in Christina Aguilera’s life since the release of her first album in 1999. She’s had two children, gained and then lost around 40 pounds, and has reportedly also gone under the knife. No matter what her body has gone through, she’s always been persistent in looking like the diva she is.

She recently turned 40, marking two decades since her first album’s release. Between 2019 and 2020, she had a residency in Las Vegas, The Xperience. In 2021 she even took part in the Demi Lovato: Dancing with the Devil docuseries. She’s currently engaged to Matthew Rutler, whom she’s been dating since 2010.
