The actor has also warned he will humiliate the actress by turning up for a public showdown at her film's upcoming world premiere. "He's has taken the break-up really badly," the Sun quoted a source, as saying. "He's spent the week in the pub texting Sienna - begging her to change her mind. His hurt has turned to anger and he has said he will sort Matthew out when he sees him. He's raging.
"Sienna has lost her rag too. She's refusing to return his calls and Rhys has promised to confront her when Matthew is with her. "His last message said he'd ruin her big night at the premiere. She thinks he's serious," the source added.
