Christina Aguilera recently flaunted her incredible figure after losing 40lbs over the years.

The 43-year-old songstress showed off her weight loss as she put on a dazzling display during her Las Vegas residency opening show.

She previously said she ‘hated being super skinny’ and has started embracing and ‘loving my new curves’, according to Health.

After years of fluctuating back and forth, she is now maintaining a slender and strong physique while ‘having a booty’.

Her secret has been dedicating herself to a healthy, balanced diet and a rigorous exercise regime.

When she welcomed her son Max, now 15, in 2008, she was subjected to scrutiny over her weight gain.

Two years later, she started losing weight for her role in her 2010 film Burlesque.

However, that same year, her weight fluctuated again while going through a divorce from music composer Jordan Bratman, 46.

The Beautiful hitmaker also shares nine-year-old daughter Summer with her longtime fiancé, Matthew Rutler, 38.

Following her son’s birth, she reportedly dropped 40lbs by restricting her daily food intake to 1600 calories and following the Rainbow Diet.

As part of her diet, she sticks to a plant-rich regime and consumes brightly colored fruits and vegetables every single day.

She has since given up on dieting and focuses on eating clean now, she revealed to L’Officiel Italia in 2020.

She noted that instead of being restrictive, she tries to consume more of whole foods and less of sugary snacks.

Besides her balanced diet, she also likes to stay very active and do a wide-ranging workout routine to keep fit.

She reportedly enjoys yoga, boxing, strength training as well as cardio exercises and will workout two to five times a week, according to In Touch Weekly.

She has also trained with celebrity fitness coach, Tee Sorge, to incorporate weight lifting and cardio to maximize calorie burn and maintain her curves.

In 2008, her trainer revealed to Glamour that she worked out ‘up until she was eight months pregnant and then started back up a few months after [her son] Max was born’.

In February 2012, Aguilera spoke to Marie Claire and said she is now at peace with her figure. She said she blocks out all the noise and only cares about feeling good in her own skin.

‘I’ve been through my highs, I’ve been through my lows,’ she said at the time. ‘I’ve been through the gamut of all things in this business. Being too thin. Being bigger. I’ve been criticized for being on both sides of the scale.’

At the end of the day, she said the only opinion she pays attention to is her own.

‘It’s noise I block out automatically,’ she added. ‘I love my body. My boyfriend loves my body. My son is healthy and happy, so that’s all that matters to me.’

She noted that she also stopped weighing herself and quit restricting herself as she did in the past

‘I happen to be very confident in my own skin,’ she continued. ‘It takes time to get to that place, but it’s all about embracing yourself and your body’; seen in September 2012

She noted that she also stopped weighing herself and quit restricting herself.

‘When I worked on Burlesque, I lost so much weight that I was too skinny,’ she said. ‘I don’t weigh myself — it’s all about how I feel in my clothes.

‘What looks good on one person might not look good on another body type,’ she added.

‘I happen to be very confident in my own skin,’ she continued. ‘It takes time to get to that place, but it’s all about embracing yourself and your body.’
