The Sun has reported that Interview beauty Sienna Miller has dumped her Welsh actor fiancé Rhys Ifans because he is jealous of her friendship with her ex-boyfriend Matthew Rhys. Sienna and Matthew have been spotted together while she has been filming in Los Angeles and it seems Rhys is suspicious that they may be more than just friends. Apparently Sienna called Rhys Ifans, who's working on his new film The Boat That Rocked in Bristol, last weekend from Prague to tell him the bad news. A source tells The Sun, "Things have been awkward for a while after she caught Rhys going through her text messages. She went bananas and Rhys said he was looking for what he called ‘incriminating evidence'."
