Britney Spears shared a video of herself flaunting long hair, while wearing bikini bottoms.

The 40-year-old singer took to Twitter on Wednesday to share the 36 seconds-long clip, where she can be seen posing in front of the camera.

In the video, she is seen wearing a pink bikini bottom and heels. Someone is holding the camera for Spears as the singer does a little walk, while the former moves backward.

"First time having really long hair !!!" she captioned the video. "It's different ... serving evil mermaid vibes I guess 🧜‍♀️ 🤔😉 except I have legs 😏 !!! Pss too hot to go outside bored as hell 🙄 !!! Psss this is not a hair commercial."

Social media users shared their reactions in the comments section, with many criticizing the singer for her lack of clothes.

"Can't believe I'm saying this but please put some clothes on idk what ur selling but nobody buying," one of the users commented.

Another one wrote, "Britney, you don't need to flash almost all.... I feel so sorry for the young girls of today, they think the only way to get attention is to show all, come on, be a role model, beauty don't have to be handed on a plate....."

Many people also came out in support of Spears, whose conservatorship was terminated in November.

"You were my first ever celebrity crush and I'm so happy to see you finally free to do whatever you want," one of the fans wrote.

Another one added, "she just regained her basic human rights and autonomy over her own body after it being stolen from her illegally for 15 years. Give grace. She is just beginning to heal from traumas that would destroy you."

Spears shares two kids - Jayden, 15 and Sean Preston, 16 - with her ex-husband, singer Kevin Federline. The former couple were married from 2004 to 2007.

Federline opened up about Spears during an interview with 60 Minutes Australia Wednesday. In the sneak peek of the interview, Federline shared why he didn't speak up during conservatorship, and how he feel about it now.

"I was mortified for her. I really was. I still feel bad," he said. "The boys, the boys, the boys. I had to worry about them. I couldn't get involved."

The complete interview is slated to release Sunday.

Spears is now married to Iranian-American model Sam Asghari.
