Vanity Fair is reporting that the broken-hearted blonde is on leave from her marketing job to allow her to handle her breakup as privately as possible.
The magazine is also reporting that Cressy was supposed to attend the society wedding, which is being held in Memphis, but pulled out last minute after the news of her split.
"Cressida can't stand the fact that everywhere she goes, someone takes a picture of her on their smartphone especially when she is feeling down," a source told the publication. "She has been told it's O.K. for her to take some time off work."
