Right from the start when the gorgeous Sienna Miller got together with fellow actor Rhys Ifans people quite unfairly judged them as "the beauty and the beast" couple.Yes, he always looks like he needs a good wash and Sienna always scrubs up very well.
Because it's always been rumoured, but never proven I hasten to add, that she did try and get him to alter his style while they were together.
The fact that she always leads the fashion pack - and he didn't even bother to follow - might’ve irked her.
You know what it's like when a person is into fashion - it becomes part of their lifestyle and maybe Rhys just wasn't that interested.
I also suspect that she may have been more driven than he was, although of course I can’t know that for sure.
But what makes me feel that is the way Sienna has relentlessly pursued her career and it is hugely professional about showing up for every red carpet event and keeping her profile high.
Whereas Rhys has often been photographed antagonising the paparazzi and trying to get them to leave him alone.
When these basic mismatches occur in a couple then I usually find there's a domino effect.
One thing that they take a different approach to actually spins out into other things and so on.
Like a set of dominoes falling they come to realise that one thing after another they’re not very well matched on.
