We’re hearing reports that Sienna Miller has ended her year-long relationship with Rhys Ifans — apparently because he was jealous of her ex.

According to Britain’s The Sun newspaper, Sienna dumped the Notting Hill star over the phone at the weekend.

Their source said that Sienna, 26, had lost her patience with the Welshman, who she has been dating for nearly a year now, because he didn’t like her spending time with old flame Matthew Rhys.

The Alfie star broke things off with Matthew, 33, another Welsh actor, when she started dating Rhys in 2007.

But the exes have recently shot a movie, the Edge of Love, together and are said to have been hanging out in LA.

She has denied that there is anything going on between her and the Brothers and Sisters actor, but Ifans is said to have been obsessing about their relationship.

Rhys, who is shooting a movie with Philip Seymour Hoffman in Bristol, England, right now, is said to be "heartbroken".

The source told the paper: "Sienna broke the news at the weekend in a call from Prague.

"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’. He has been giving her a hard time lately, questioning her commitment to him and the time she puts into the relationship.

"She compared him to a spotlight shining in her face all the time. He is heartbroken they have split. Sienna feels really sorry for him because he had slotted into her family perfectly, but she couldn’t cope with his suspicious and jealous behaviour.

"When they are together they get on so well. But she can’t cope with his jealousy."

Requests for comment from Sienna’s rep have not yet been returned.
