There was also a photo with her partner Matthew Rutler as well as a cute picture of their little dog. The star was then seen with Megan Fox and her boyfriend Machine Gun Kelly, as well as Jason Derulo.

“About this weekend,” was all she wrote in her caption upon noting that she was in Las Vegas.

In January, Aguilera celebrated her return to Las Vegas following 10-month The Xperience with Burlesqueier in 2019.

It is an intimate show at the Venetian Voltaire Belle de Nuit, a newly opened venue.

Additionally, Aguilera added new shows to her residency this week. Voltaire Bell de Nuit at The Venetian announced that ten new dates have been set for Aguilera's series, which runs from April to August.

That includes two shows that were postponed from January and Aguilera canceled due to illness.

Tickets for the new shows will be available on Friday, February 16th via voltairelv.com.

Fans who had tickets for the original dates in January will receive ticket purchase information prior to the public on-sale date.

Swift received the most nominations for her acclaimed album “Midnights” and its single “Anti-Hero,” which received some of the best reviews of her career.

This track is nominated for the Record of the Year category, a category that honors the artists who recorded the song as well as its producers and engineers, as well as the Song of the Year category, which honors songwriters. The SZA track Kill Bill was also nominated in both categories.

Swift has already made history in the Album of the Year category and is currently tied for three wins with music legends Frank Sinatra, Paul Simon and Stevie Wonder.

However, she is now poised to become the first person ever to win the category four times if Midnights emerges as the winner this year.

She recently showed off her incredible figure after losing 40 pounds over the years.

The singer showed off her weight loss as she made a stunning appearance during her opening night show in Las Vegas last month.

According to Health, she previously said she “hated being super skinny” and began “embracing and loving my new curves.”

After years of bouncing back and forth, she now maintains a slim and toned physique while “having a booty.”

When she gave birth to her son Max, now 15, in 2008, her weight gain came under scrutiny.

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

However, that same year her weight fluctuated again while she was divorcing music composer Jordan Bratman, 46.

The “Beautiful” hitmaker also has nine-year-old daughter Summer with her long-term fiancé Matthew Rutler, 38.

She reportedly lost 40 pounds after giving birth to her son by limiting her daily food intake to 1,600 calories and following the rainbow diet.

As part of her diet, she pays attention to a plant-rich diet and eats colorful fruits and vegetables every day.

She has since given up the diet and is now focusing on a clean diet, she revealed to L'Officiel Italia in 2020.

She found that instead of being restrictive, she tries to eat more whole foods and fewer sugary snacks.
