Amy Winehouse's Dad Mitch says that reports that his daughter's marriage aint going so well is absolute rubbish, apparently. Mr Winehouse is quoted by IMDB.com as saying that the pair are happy and in love: "[Blake is] the perfect son-in-law. Blake is a traditional man," he says. "He asked me one night if I would mind if he asked Amy to marry him. I told him I didn't mind at all and to go for it. I liked him for what he did. It showed respect towards me and Amy. He's been very good to her and I was happy to welcome him into the family. Amy loves him and that's what's important. I've never seen her as happy as she is at the moment. All this stuff about her and Blake arguing and not getting on is a load of rubbish".
So there you go. Dad has spoken. So stop all your speculating.
