The 'Oops I Did It Again' star hasn't confirmed the break up but multiple reports in the US claim the pair have ended their eight-month relationship.
Britney has deleted photos of Charlie from Instagram.
The mother-of-two began dating producer Charlie around October last year and he joined her on the red carpet at the Billboard Music Awards in May.
Brit told People earlier this year: "I'm the happiest I've ever been."
She also said her children Sean Preston, nine, and Jayden James, eight, got on with her boyfriend: "They relate to him really well and they have fun together. He's refreshing to be around and really light-hearted."
A source even told us the couple had been talking marriage.
The insider said: "Britney and Charlie feel like soulmates and plan to marry soon. Even though they could invite hundreds of people, it's just going to be immediate family and friends - probably 60 people at most. Britney has learned the value of a simple life."
