Britney Spears is on the dating app Tinder.

The 'Toxic' songstress shocked 'The Tonight Show' viewers who weren't expecting an appearance from the blonde beauty on Tuesday (08.09.14), but it was the host who managed to surprise everyone, after he announced to an unwitting Britney that he had created an online dating profile for her.

The newly single singer broke up with her long-term partner David Lucado in August, but she was in good spirits as presenter Jimmy Fallon joked about the app - which allows users to approve potential dates by flicking through their profile photos - and even took part in a 'Dating Pros and Cons' segment on the show.

When asked if she was excited to be on the dating app, Britney sarcastically said: ''Oh yeah, I'm thrilled.''

The duo then started their skit, which included references to Britney's pop career and her new lingerie line.

Talking about the pros to dating Britney, Jimmy said: '''I'm Not a Girl, Not Yet a Woman' is a great song.''

The 32-year-old pop star quipped: ''It's also Jimmy Fallon's yearbook quote.''

He then praised Britney's new business venture, saying: ''Today she released a brand-new sleepwear/lingerie line called, 'The Intimate Britney Spears', and it can be worn by anyone.''

The singer then grimaced as she added: ''Jimmy's wearing it under his suit right now.''
