The source told the Daily Star: "She's absolutely smitten with him and keeps saying he's the one. It's getting very serious very fast."
Bruno Mars is rumoured to be dating Amelle from Sugababes / WENNHow serious? How fast? "She has been through a lot and Bruno is really making her feel special again. Who knows what will happen next? None of us would be surprised if they got engaged."
Sorry, what?! We just spat our tea out in shock. Engaged? Nooo, Bruno is not allowed to be engaged to anyone other than us and that is a fact.
