Britney Spears Goes Braless In Her Nightgown During 'Throwback Week' 

Singer Britney Spears has announced the start of "throwback week" on Monday night!

The 41-year-old pop star shared four photos and videos with her millions of Instagram followers on Monday night, but it was really the last one that caught her followers' attention.

In her latest Instagram post, the “Hold Me Closer” singer shared a single photo that featured her standing in the living room in a thin white nightgown. It’s clear that she is braless under the thin material as she lets her long blonde hair cover at least one side of her chest.

In the caption, Britney wrote, “Remember when I played and married myself ??? !!! It’s throwback week for me ? !!! Psss I’M SITTING ON TOP OF THE WORLD Y’ALL !!! Y’all can laugh now ??? !!!”

Britney tied the knot with Iranian actor Sam Asghari last June after they met on the set of her “Slumber Party” music video in 2016. However, Britney has since been talking about “marrying herself” in several posts.

Fans aren’t quite sure what she means, but with comments disabled since the start of the new year, fans have had to go elsewhere to debate their theories. That being said, that was far from the only Instagram post that Britney shared on Monday night.

In her one and only dancing video posted on Instagram Monday night, the “Overprotected” singer shared a video of her dancing in her new favorite spot… the gym! Her long hair is tied back in a messy bun as she dances in white shorts that are rolled down around her hips.

She dances barefoot in an orange tank top that she pulled up and folded over her chest to show off her core. The music in the video was set to Omah Lay and Justin Bieber’s “Attention.”

In the caption, Britney wrote, “Lame ? !!! Reposting to remind myself to stay AActive [sic] ???? …”

It’s not clear what the dancer finds “lame” about her video, but it seems she might be having trouble finding the motivation to keep dancing, given her next post about cardio.

Although a dance class is definitely a lot more fun than running on a treadmill, it seems the singer is not a fan of cardio.

She shared a relatable meme of a young child appearing to give the middle finger while the text around the photo reads "When someone says they enjoy cardio."

Although the "Lucky" singer has said in the past that she sometimes dances for hours a day, she wrote in the caption of her dancing video that she has to "remind myself" to stay active.

As fans can see from the screenshot, Britney didn't share write anything in the caption. However, she did share another post that hinted at how she plans to spend her summer!

In her first post on Monday night, the "Oops!...I Did It Again" singer revealed that she was looking forward to gardening outdoors again when the weather is warmer.

She shared a photo that she credited to @vladamua that shows a pair of green lips painted to look like leaves biting down a miniature red gardening can.

In the caption, Britney wrote, “Can’t wait to get into my garden this summer ? !!!” Britney is still living in her Thousand Oaks mansion that she has lived in for years and sold off the home she bought with Sam Asghari last June for nearly a $2 million dollar loss.

Plenty of fans have been wondering if the “Toxic” singer planned to move into her new home in Calabasas. On Sunday night, Britney revealed that she did… and then promptly moved back to her Thousand Oaks abode after a few months.

In a lengthy Instagram post, Britney said that her Thousand Oaks home is "pretty big" and described the Calabasas mansion that she has since sold off as "pretty."

"Most would say it was by far a more beautiful home … but I stayed for 5 or 6 months and came right back to my normal bedroom ?️ ... I like what I like and that's okay," Britney wrote in the caption. "Nobody can tell me what is the best for me … they can give me their advice if I request it … but l’m in love with the life I have built for myself !!"
