Britney Spears has injured her knee after falling down stairs

She wrote on the Instagram post: "My boys had to leave and go back to Maui.

"This is the way I express myself and pray through art... father who art in heaven... I'm not here for concern or pity, I just want to be a good woman and be better... and I do have wonderful support, so have a brilliant day !!!

"Psss I fell down the stairs at my friend's house... it was horrible.

"It snaps out now and then, not sure if it's broken but for now it's snapped in !!! Thank u god.(sic)"

Britney's infamous dancing videos have worried fans in the past.

In August, commenters online expressed their concern at her messy house, with what appeared to be dog poop and other clutter on the floor visible behind where she was dancing.

Britney could be seen in the video singing her own version of Prince song Kiss as she danced in her pyjamas, which were made up of a brown polka dot bralette and mini white shorts.

A puppy could be seen in the background, and at one point she sang: "I don't know who I am, oh, oh."

In the caption, she quipped: 'I would say, Julia Roberts singing Prince's 'Kiss' off key a touch, but I sounded really good behind the lens lol!!!

"PSS Wise a**es, I do know who I am !!!

"I have eight different languages written on my neck... these are my pjs, but I put these boots on to play with lighting ... not the most elegant look but hey!!! (sic)"

In another video, Britney revealed she was in the middle of cleaning her house but took a quick break.

She wrote: "Messing around with lighting and cleaning my house like no tomorrow,' the star wrote in the caption."

Some people are concerned by the video, which had comments disabled but was shared by a fan on X.

Echoing another user, a fan asked: "Is that dog poop on the floor?!"

Another person suggested she "needs help", while a third said: "You can't help but feel sorry for her."
