Britney Spears Proves Her 'Hips Don't Lie' In Latest Instagram Video!

Singer Britney Spears is practicing her hula dance!

The "Circus" singer was hard at work on Instagram, dancing it out for the camera in a bright yellow bra with black booty shorts. Check it out!

Britney seems to be a fan of the color yellow, as this isn't the first time she's been dancing - or working out - in bright yellow. Considering the sunshine in Maui, it's definitely appropriate!

"Yellow hello ? !!!! " Britney began. "So the gym in Maui ? was beautiful and working out is way better in Maui especially when you can squeeze in 'Hips Don’t Lie' movements outside by the fountain ⛲️??? !!!!"

"Pssss had to do the hula dance !!!" Brit added. It's unclear if she's been to a luau - we'd love to see the pics! - but we know where there is one place that Britney's been heading recently... the gym!

Britney Spears posted a video montage that was almost 90 seconds long!

In the video, she can be seen dancing and working out on a treadmill, whooshing her hair around, lat pulldowns, dancing, chest presses, shoulder presses, leg abductions, headstands, dancing, inchworms, pushups, yoga poses, weight lifting, and hip-shaking... and did we mention dancing?

Britney makes gym time seem like so much fun!

"So I was a little too excited for my trip to Maui ? !!!!" Britney wrote in the caption.

"I might have over done it a bit ???‍♀️ …. I mean I was extremely excited to be there !!!!" she added. Fans can definitely tell!

"Here’s me at the gym ?? doing an intense workout … I’m sweating A LOT ? !!!!" she wrote.

"Honestly after being that sick before I have the need to survive in a different way !!!!" she added. "Being present in the utmost way ✨!!!!! Pushing it just a TOUCH does wonders in my opinion…God speed … God speed ??‍♀️? !!!!!"

Wait... sick? That's right1 Did we forget to mention that some fans think that Britney might be pregnant!

Last week, Britney posted a photo with her hands on her stomach in what some fans think is a heart shape.

“Here’s me playing in my new dress ? !!!!” Britney wrote in the caption. “If I ever did a clothing line it would be similar to this !!!! When I got to this farm, I took my shoes off and ran ??‍♀️ … I’ll have shoes on next time ??‍♀️?? !!!!! Pss… This is me trying to pose for a pic !!! I tried ??‍♀️?”

So no mention of a pregnancy there, but there was plenty of chatter in the comments!

“baby? Her hands on her belly,” another commented.

“I saw it and am thinking she’s hopeful!” another offered.

“yep! And she’s wearing baby blue,” another fan pointed out.

“my eyes damn near fell out of my head when she did that ?” a fan said.

“yupppp. I caught that as well,” said another.

“I was looking for this comment!” wrote another. “I rewatched it 3 times bc I saw that ???she totally holds her belly momentarily too.”

“Plus she just mentioned in her last post she was throwing up and nauseous ?” said another.

Although Britney has been enjoying her time in the sun and getting a killer tan while she's at it, she said that she's also been feeling a bit sick lately!

“I think I have a small bug …” Britney wrote. “the only thing that is similar to this feeling is when I was pregnant … it’s the nausea that is the worst … “

“It’s like I can’t wake up so I go to the gym trying to wake my system up !!!” she continued. “It’s like clock work … I break my first sweat then I go to the bathroom and throw up … it’s absolutely horrible but then I stay at the gym because I don’t want to go home and lay sick in bed.”

Some fans say that Britney might be experiencing morning sickness... but we won't know for sure until Britney breaks the news herself!
