(femalefirst.co.uk ) - Jude Law is reportedly devastated ex-fiancee Sienna Miller is dating his friend Rhys Ifans.
The Hollywood heartthrob - who split from the stunning actress last year following his affair with his children's nanny - was hoping to rekindle his romance with Sienna but has recently realised she has moved on.
Jude is said to be dreading seeing Sienna and Rhys on the London party scene and is doing his best to keep a low profile.
A source said: "Jude is still pining for Sienna and now that she is besotted with one of his best friends, it has really hit home.
"Jude has told pals he doesn't want to go out in London because bumping in to them would be too awkward. At a push he will go to the Groucho Club, but he always checks first to see if Sienna and Rhys are likely to be there."
Jude - who reportedly disapproved of Sienna's partying lifestyle - is also said to be concerned about how well the 'Factory Girl' star and the 'Notting Hill' actor are suited.
The source added: "Jude is on the edge because pals have told him how he and Rhys are total opposites. Rhys is a great party companion for Sienna, but Jude didn't like the high-octane lifestyle."
