She also insisted she’s actually “boring as hell” and doesn’t drink alcohol because she’s realised she doesn’t like it.
The Toxic star added: “I’m not this girl or that girl … I am River Red … and being able to volumise my voice in a world where I lost my rights … for 15 years … gives me an opportunity to succeed !!! ...
“I feel younger and in awe … unfortunately I’m boring as hell and drink hot chocolate at night!!! I’ve waited nearly 15 years to drink alcohol only to realise I hate it !!! It makes me sad and I feel bloated, although food tastes better ... Stay blessed and driven … "
Spears finished her message by writing: “PS yes I took my Instagram down and now it’s back up because I can!!!”
The singer previously slammed the fans who called police to her California home after she took down her Instagram page - insisting they “went too far”.
She said in a statement shared on Twitter: “As everyone knows, the police were called to my home based on some prank phone calls.
“I love and adore my fans but this time things went a little too far and my privacy was invaded.
“The police never entered my home and when they came to my gate they quickly realised there was no issue and left immediately.
“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 I care so much about can respect my privacy moving forward.”
