His brother is married, all of his pals are married, Harry is just ODD MAN OUT, and this TART got her hooks into him.
But the thing is....IF she really was preggers, she would be showing ( this article is from mid December, for crying out loud! ) and there have been very recent pictures, in London's the Daily Mail, of the two of them, out and about, recently, with her wearing skin tight/as though they had been painted on her naked body jeans. There was NO "bump"!
