Chris Brown's Girlfriend Chills in SEXY Bikini With A Mystery Guy

Looks like Chris Brown knew exactly what he was talking about when he sang the song "Loyal".

The singer's on/off girlfriend was seen enjoying the sun and having fun on Miami Beach with a mystery man. Karrueche looked quite ravishing in a black and white bikini which showed off her flat belly and gorgeous legs among other things.

If Chris Brown is still interested in this beauty, then he better put a ring on it because it seems these men ain't loyal either!
