Rihanna says she's "crushed" at missing Katy Perry's wedding.
In a US radio interview the star said, "I am crushed that I missed that," she said. "I will never, ever forgive myself."
Work commitments meant that the 22 year old was unable to make the trip to India where she was expected to be Katy's maid of honour.
A lack of phone and internet connections was one of the primary reasons that Ri-Ri stayed at home.
Katy and Russell Brand tied the knot on October 23rd in Rajasthan, India.
However it doesn't seem to have damaged their friendship as the pair are set to collaborate on a track in the New Year.
