Sienna and Rhys about to split?

Actors Sienna Miller and Rhys Ifans are said to be on the verge of splitting up, according to pals. It seems that Sienna has lost that loving feeling.

A source told Grazia magazine: "It's awful but everyone who knows them can just see it coming a mile off. Rhys seems madly in love with her still, but everyone is speculating Sienna has grown out of the relationship.

"It's almost painful to see them together because they've gone from being the perfect couple to him looking as if he's struggling to keep her attention. It's so sad." They added.
