Shortly afterwards, a representative confirmed the news.
It has been reported that Britney heard rumours of a video being shopped around that showed David being unfaithful with another woman, prompting her to end their 17-month relationship.
Britney, 32, and Virginia-raised lawyer David started dating in March 2013, just a couple of months after she and her former agent Jason Trawick mutually ended their engagement.

Speaking in November, the singer declared, "I'm in love" as she opened up about her boyfriend.
"He’s just a simple man. I adore him," she told Entertainment Tonight. "He's really funny and he's really passionate. I love the fact that anything he's involved in he's passionate about and it's contagious."
Now, Britney is keeping the focus on her two beautiful boys, Sean, eight, and Jayden, seven, and her ongoing Las Vegas show. But a source told E! News, "She is heartbroken".
"She will get through it," the insider added. "She's a strong girl and he was never right for her."
