Cher Lloyd engaged?

I nearly choked on my chicken when I read the headline Cher Lloyd is engagaed!!  The Swagger Jagger singer  18 and he's 21 .... whats the hurry? Im never one to like breaking up the party and doing the right thing - but why dont they try living together first - at their age this is best, well in my eyes... this is heading to be another statistic.... but I really do hope they prove me wrong!!
