Britney Spears flaunted her toned figure while modeling a stylish swimsuit as she gushed about losing ‘2 inches in my waist’ in a new clip posted on Thursday.

The Baby One More Time songstress, 42 – who recently reunited with ex-fiance Jason Trawick during her latest Las Vegas trip – could be seen filming herself in the reflection of a large mirror bordered by lights.

She donned a white, shell bikini top that was held up with thin straps as well as a pair of matching bikini bottoms.

The Princess of Pop slipped into a pair of closed-toed, black heels that offered a bit of color contrast to the look.

Britney added a tan hat on top of her head which partially concealed her blonde locks.

Spears opted for minimal accessories, and added a black, beaded necklace.

In the caption, Britney penned, ‘Ok so I’m proud of my white shell bathing suit and that I lost 2 inches in my waist!!!’

‘This is actually a different edit of my swim suit video but I thought it’s particularly weird … I sort of disappeared through the edit!!!’

The singer continued, ‘When I shot it I remembered saying I didn’t do anything different why did my body turn into a ghost??? Who knows!!!’

Her latest Instagram reel comes shortly after Spears whisked herself away for a getaway to Las Vegas with her brother, Bryan.

She shared various clips on social media that had captured special memories from the trip, including visiting a luxury spa.

Britney documented a few moments during the relaxing afternoon – but sparked concern from fans while speaking in a childlike voice throughout the course of the reel.

‘My brother, we’re in Vegas and we’re going to the spa and we’re lost,’ she could be heard saying while filming the pair strolling through a lavish lobby.

Upon approaching the front desk with Bryan close by in front of her, the songstress stated, ‘We have a scheduled appointment for [4pm]!’

While waiting to be taken back, Britney filmed the decorated lobby and excitedly exclaimed, ‘It’s like we’re in Disneyland for adults!’

‘This is like going to a spaceship,’ she added to her brother who was sitting nearby. The star then noticed decorative lights that covered the ceiling and added, ‘Balls. A lot of balls. Hello balls.’

Spears was soon led down a hallway that was also decorated with lights and she said, ‘I feel like I’m tripping dude! This is better than Disneyland, cause it’s 𝑠e𝑥y.’

However, the attendant that was guiding the pop star into a room informed her that filming was not allowed beyond that point.

The clip jumped to later in the day as Britney spent time in her hotel room and struck a few fun poses with her brother.

Another video was taken as the star dressed to impress in a fitted, red strapless minidress before enjoying dinner with some of her close pals.

She captioned the reel with: ‘Dinner with friends,’ followed by pink flower emojis and quickly filmed herself in the reflection of a bathroom mirror to showcase her outfit.

Spears later flaunted another look during the vacation while donning a figure-hugging, hot pink minidress – which she also modeled for her followers.

During her Vegas getaway, TMZ reported that the Toxic hitmaker reunited with her ex-fiance Jason Trawick – but insiders claim that the pair are just friends.

According to the outlet, both Britney and her brother, Bryan, still remain close to Trawick and made plans to meet up at Resorts World Las Vegas.

Jason was the pop star’s agent and the pair began dating in 2010 and became engaged the following year. However, the former couple split in early 2013.

Trawick was also a co-conservator during a portion of their relationship until they broke up.

Britney updated fans about her Vegas trip on Instagram, and revealed that she caught a cold while reflecting on the vacation. ‘So weird !!! I had a wild trip to Vegas and got a cold again !!! I really liked jamming with my brother !!!’

‘He fed me Alaskan crab and I realized I wasn’t alone at 3:00 in the morning during a night drive where I saw more people on the strip than I’ve ever seen in my life !!! It was pretty cool !!! I met up with an old friend then realized how interesting time is!!’

‘And to what makes it in my head speed up or slow down !!! What feeds your soul or what serves you interest and what makes you really want to participate in this game we call life !!! Or is it a game at all ???’ she questioned.

Spears stated that she ‘had enough balls to serve any running season but most of the time I sat on the bench and never played at all because by observing…’

‘Something so different and wrong and broken so they might understand how completely destroyed I really was !!! So I strike out and go to bed and have a secret,’ Britney further shared.

The star also expressed that when traveling, she has ‘rosemary, tea tree oil, my two new favorite face wands, and candles,’ while adding that, ‘it’s important for all women who have witnessed real madness of life to take time to reset, regroup, and manage yourself in finding ways to heal your body !!!…’
