I can't understand why the sis-in-law is doing a tell all to the papers? Would she not just go up to Giggs' wife on the quiet and say....look he's been fooling about with me too, sorry about that, but you really should kick him out. Rather than going to the local rag and selling it to them? Unless of course she hates the wife, but even still, to go have an 8 year affair with your brother in law and then to sell your story, disgracing yourself and your whole family, makes you a bit of a skank.
