Britney Spears has worried her fans after teasing that she will release an 'adult' video this week.

The Toxic singer posed naked on her bed and teased that an X-rated video would "premiere" this week. The mother of two, 40, is no stranger to showing off her body online and stripping off but her latest snap has sparked concern, reports the Mirror.

Sharing the nude snap on Twitter, she captioned the suggestive pic: "I have a premiere for a movie this week 'The Legislative Act of My P***y'.

The announcement was posted alongside a sped-up a video which Britney captioned: "Thought I had good hair today." She added: "Ps I've been holding my cousin's new born baby all day with this baby holder on... I'm literally in a dream."

Britney was released from a 13-year conservatorship last year, and has made the most of her newfound freedom with her own form of self-expression. This can sometimes manifest in nude snaps and a series of eccentric posts on social media.

Britney first posted the news on Monday earlier this week, but fans were quick to pick up on the fact she had posted the video multiple times that day. One fan said "She keeps reposting, but everyone says she's fine, nothing's wrong - something is wrong!"

Another said: "And here we go again. But y'all love to pretend like it's normal. This is like the fourth time she posted this today." A third penned: "What are we not getting...", prompting a user to respond: "It was filmed in her old living room! That's as far as I got so far. But the living room is from her old house... old video?"

Britney's bed snap has once again been posted earlier this morning, alongside the same caption as before, suggesting the 'movie' is being posted this week. Some fans have been quick to defend the popstar, suggesting that there's no cause for concern and that a NSFW video from Britney would be 'no different from the Kardashians'.

One follower Tweeted: "The girls that get it, get it… the ones who don’t, don’t … to all the people in the comments and say they feel sorry for her kids do you say that about every other celebrities children that’s a woman that dresses sexy and models for whatever? Where’s that same energy?

"I mean their mom is Britney Spears for God sakes I need to get over it they’ll be OK … why don’t we have the same energy about the Kardashian’s children? Like some of y’all in these comments on IG & here are a bunch of hypocrites seriously it’s annoying."

While another said: "Y’all haters need to stop with the hate already. Britney is fine. If she wants to show off what god gave her that’s her business. Don’t like it? Unfollow and block her. It’s that simple."

Although, one follower replied: "Kardashians were naked from the beginning. We all know they have no other talent/skill to make money. Britney is the queen of pop for a lot of us 90s kids. Our only worry is does she need to do this? We all know she is paid for each tweet/post. Is she that desperate?"
