The love affair between British actors Sienna Miller and Rhys Ifans is over, with multiple sources claiming Miller dumped her 39-year-old beau because of his “jealous and mistrusting ways”.

According to one source, the Alfie star broke up with Ifans over the phone from Prague last weekend, citing their “long-distance relationship” as the reason for the split. However, a pal of Miller’s insists Ifans was really dumped because he’d questioned Sienna’s faithfulness in recent times, and the long-distance issue was just a cover for the media.

“When they are together they get along so well, but she couldn’t cope with his jealousy,” a source told Britain’s The Sun newspaper.

The last straw came for Miller when she caught Ifans “going through her text messages”. Apparently, the Notting Hill star was certain his blonde girlfriend was hooking up with her former flame and Edge Of Love co-star Matthew Rhys, and wanted to find the proof in order to put truth in his accusations.

A pal of Miller’s revealed that the 26-year-old actress had admitted to Ifans that she’d been seeing Rhys “regularly” in recent months, but denied she was having an affair with the Welsh actor.

The Gumby/Slutienna pairing looks set to finally come to an end, with reports surfacing in the U.K. that Slutty-Miller is sick and tired of Gumby-Ifans’ jealous ways, and even went so far as to compare him to her ex-Jude Law during one huge bust up recently.

According to a source, Miller has been struggling to cope with Ifans’ possessive streak, something that has come out more and more in recent times. His controlling behaviour reminds the actress a lot of her former partner, Jude Law, and friends of the couple have revealed that Miller has reached breaking point, and wants out of the relationship.

“Rhys gets very jealous – he hates [Sienna] socialising with other men and always wants to know where she is and who she’s with,” one friend said. “During a [recent] row she yelled at him: ‘[Being with you is] just like being with Jude.’”

Added the friend: “Rhys freaked out, because he prides himself on being the laid-back opposite of Jude. But he just gets worked up seeing men admiring his girlfriend and trying to hit on her.”

The couple’s work commitments have also gotten in the way, with Sienna’s constant filming in the U.S. and Ifans’ in the U.K. putting a strain on the relationship.

A source explained: “They had a huge bust up recently. Sienna promised to spend a week with Rhys. He arranged his filming schedule, but at the last minute she canceled her trip, saying she had to work. Rhys hit the roof when he called her and found out she was partying in LA.”

Another source added that the rift in the relationship has very little to do with Ifans’ jealousy or Sienna’s work abroad, claiming that Miller has simply “grown out” of love with Rhys.

“Rhys still seems madly in love with her but everyone’s speculating Sienna has grown out of the relationship,” the source said.

“It’s almost painful to see them gone from being this 24/7 love-fest to [Rhys] looking as if he’s struggling to keep her attention. It’s so sad.”

In early March, The Mirror reported that Miller and Ifans were engaged and planning a Summer wedding; however, later that same day, Sienna’ rep denied the rumours, stating that they were totally “untrue.”
