After breaking up with her
Even at one of her Vegas shows, Spears says “So I know you know my boyfriend cheated on me."
So, because Jimmy Fallon is Jimmy Fallon....he decided to put good ol' Brit-Brit on Tinder because that's what you do when you've just broken up with a longtime love.
It's nice to see Britney is just like one of us!
But of course, she'll find someone super fast because she's Britney.
