Was Sienna Miller cheating on Rhys Ifans: Notting Hill star angry?

Rhys Ifans has been taking things pretty bad at the moment since his break-up with Sienna Miller; he has now blamed the break-up of the relationship over her ex. The couple split due to Ifans being very jealous over Miller spending time with her ex Matthew Rhys, Miller decided to call things a day and as a result Rhys Ifans has taken the news hard and has hit the bottle hard.

The Notting Hill star is convinced that his ex has started to see her ex Matthew, again and has threatened that he will punch his lights out. He also said that if he does find out that Matthew and Sienna are once again a couple, then he will humiliate her. He will do this by turning up at her world premiere for her upcoming movie.

It looks as though Rhys Ifans is a very angry man at the moment, he has been texting Miller so much lately, and now it seems that she has had enough, she is not returning any of his texts now.

If I was Matthew Rhys, I would be a little scared right now; although the couple might not have anything to hide Rhys Ifans is a very unstable character at the moment. The thing is, he is hurting at the moment and he just wants to lash out.
