Christina Aguilera gained weight due to numerous reasons. Pregnancy was one of them. In 2008, Christina gave birth to her first son with ex-husband Jordan Bratman.

It was during her pregnancy that she started to gain weight. Women do! Carrying a living being in the belly, looking after its well-being, and hormonal ups and downs can lead to weight gain during and post-pregnancy.

In 2009, Christina Aguilera went on a diet and lost pounds for Burlesque. She needed to look the part, and she worked with celebrity trainer Tee Sorge to achieve the look. However, Burlesque did not do well at the box office. This was a professional and a mini heartbreak. But what came next was totally personal.

  • Divorce And Heartbreak

Divorce or any kind of heartbreak with a partner takes a toll on your emotional and physical health. In 2010, Christina and Bratman called it quits. She started to regain the weight she lost.

In an interview with Marie Claire, Christina said, “I don’t weigh myself. What looks good on one person might not look good on another body type. I happen to be very confident in my own skin. It takes time to get to that place. But, it’s all about embracing yourself and your body type.”

  • Career Commitments

Christina had not even recovered from her heartbreak when the opportunity to be a judge on The Voice came knocking. She thought it was a wonderful opportunity and took it up. However, she was also trying to sell new music at the same time. With so many things on her plate, she did not pay attention to how she was feeling emotionally, which manifested itself physically. Her weight gain was constantly criticized.

During this time, Christina said, “The challenge I’ve always had is being too thin. So I love that now I have a booty, and obviously I love showing my cleavage.” But this was not the end.
