Jason Derulo's got a new girl ... and she's 50 Cent's baby mama.
Sources close to Jason tell TMZ the singer met Daphne Joy, a model and fashion designer, a few weeks ago when he was in the UK. The two hit it off and have been together ever since. Daphne and 50 have a 3-year-old son named Sire.
It's Jason's first relationship since splitting with Jordin Sparks last year.
50's known for starting social media beef so we're sure it's only a matter of time before the first shot is fired.
