Sienna Miller is postponing her wedding to fiancé Rhys Ifans, according to pals.

The couple are said to be struggling to maintain their long-distance relationship.

Sienna, 26, is filming GI Joe in Europe while Rhys, 39, is working on Richard Curtis movie Radio Caroline in Southampton.

‘It has been very strained and things are very sensitive at the moment,’ a friend tells the Mail On Sunday.

‘They are not over, but Sienna has made some tearful long-distance calls to Rhys and has confided to some of the cast on her movie that things aren’t great.’

A spokesman for Sienna refused to comment
