I have a theory that if anything happens to your ring prior to the wedding then it is a REALLY bad sign and you should just call off the wedding before going any further.

Case in point, Sienna Miller's antique engagement ring had diamonds falling out of it and it had to be repaired twice - once in February and a second time at the end of April. Hello - wake up Sienna.

Sienna's mum spoke to The Sun and said her daughter is "too angry for tears." She also said she can't say if it's over between the couple but the paper thinks the wedding is off (it's makes a better story).

The good news is Sienna continued on with her performance of Shakespeare’s As You Like It last night, "and received rapturous applause at the end." You go girl!
