"Ahhhh the single life!" the pop star Tweeted on Thursday, a sign to the world that she and Lucado are no more.
A rep for the singer confirmed the news on Thursday, telling PEOPLE, "Yes, she's single."
The Britney Jean singer and her beau have had a "tiffy" or two in the past, but things hit a wall when Spears caught wind of a video being shopped around of Lucado making out with another woman, a source tells TMZ.
Spears and Lucado began dating in March 2013 – just two months after the singer and Jason Trawick mutually ended their engagement.
By that November, the former X Factor judge was saying she was "in love".
"I'd like to have more kids, settle down ... have kids – maybe twins – and get married," Spears reportedly said last October. "That would be nice."
While her personal life has hit a bump, Spears's career is full-steam ahead. She's launching her lingerie line, The Intimate Britney Spears, on Sept. 9, and is back on stage with her live show at Planet Hollywood in Las Vegas.
