She revealed the name change in a post on social media.
Britney Spears has claimed to have changed her name to River Red. In a post on Instagram, the singer shared a picture of Mars.
She captioned the post: “A bright one … easy does it !!! Thank you, childhood friend, I found my ball … don’t underestimate the power of purity !!!
“I see right through it all … it has liquid and is wet … it’s playful and has mass !!! I changed my name to River Red !!! Yet the fire is where it illuminates … to stare at it and jump right in with no fear at all !!!! S**t. Now I have to find my FORK!!!”
Britney then solidified her new name by changing it on her Instagram profile.
It comes after the singer addressed rumours that her new tattoo was a reference to her former boyfriend Justin Timberlake.
The 41-year-old recently got a new heart tattoo, which she showed off on social media right after sharing some old photos of her and the Cry Me A River singer.
The pair famously dated for three years, and the two posts had led some fans to speculate that the tattoo may have been related to Timberlake.
However, in a new text post on her Instagram story, Spears explained: “Just to clarify… my tattoo had nothing to do with an ex in the past!!!’
“I simply did it because I wanted to!!! The pic with my ex is a time where there was less confusion on what it meant to be together… it is what it is,” she stated.
