Britney Spears fans are shocked to hear her ‘real’ singing voice in new video

Britney Spears fans have been left stunned after the singer uploaded a video belting out ‘Opps!..I Did It Again’.

In a since-deleted video, the pop star uploaded a clip of herself singing her famous 2000 song off-camera six years after last performing it live.

“Have you guys heard !!! I’m a star now mamma !!! LOL just kidding !!! Most of this sounds pretty flat … but I liked DOING IT AGAIN !!! Wait OOPS !!! That was so lame I know," she captioned the video.

"All good in the neighborhood … as most smarta**es say !!! You gotta be kidding me !!! NOPE !!! I’m not !!! Oh kiss my f**king a** !!! AND stay classy beautiful people."

The video left many fans stocked, as one person wrote: “Hearing Britney sing in her real voice on her own terms makes me so happy y’all."

Another said: “Honestly, I just love Britney's voice so much, there’ll never be anyone like her. @britneyspears thank you for still sharing ur singing with us.”

While a third shared: “She’s a server, and she’s serving.”

Shortly after ripping down the video, the singer admitted she was ‘mortified’ as she uploaded the wrong clip of herself.

In the follow-up post, the singer captured herself dancing to Drake’s ‘Nonstop’ in a gold sequin dress.

She captioned the video: “Holy sh**t !!! Mistake sh**t !!! I posted the wrong video of me singing yesterday, and once I did, I tried to play it off with the caption !!! Embrace the fall !!! Yep, and try to play it off … yep that’s me !!!!”

Spears added that she was purely playing around in the studio.

She said: “I was in the studio messing around, and I accidentally posted that version !!! Mortified, completely mortified !!! Anyway … this is my last night in my new gold dress !!! Think I need to salsa in this dress.”

The series of posts come after concerned fans called police to the singer's home to conduct a wellness check on January 24.

However, the former X-Factor judge wasn’t having any of it, calling out followers who ‘invaded her privacy’.

"As everyone knows the police were called to my home based on some prank phone calls," she wrote in a statement.

"I love and adore my fans but this time things went a little too far and my privacy was invaded."

She added that there was no reason for the visit, and officials soon left once they discovered there were no issues.

The singer added: "This felt like I was being gaslit and bullied once the incident made it to the news and being portrayed once again in a poor and unfair light by the media.

"During this time in my life, I truly hope the public and my fans [who] know I care so much about [them] can respect my privacy moving forward. All the love, B."
