Sienna Miller just can’t seem to find guys that are suitable and available to her.  Her recent romantic relationship seems to be…well…a triangle of sorts. 

More pictures after the jump…

Here’s a quick recap.  Sienna dumped her ‘fiance’ Rhys Ifans a couple months back.  Sienna is filming in the US and starts dating fellow co-star, Matthew Rhys.  Celebitchy points out that Matthew isn’t her love interest, but it is a cover for an affair that has been ongoing with HIS co-star, Balthazar Getty.  Balthazar happens to be married – or he was before yesterday – with four children.  Sienna and Balthazar supposedly have been carrying on for months….what do you think?
