Sex and the City star, Sarah Jessica Parker has admitted that rumours of an on set feud between her and co-star Kim Cattrall used to really upset her.

The show was plagued during its six season run with stories of a behind the scenes beef between the two and Parker told Howard Stern that the reports used to "really confound" her.

Parker was on Stern's radio show to promote her new HBO series, Divorce, when the host asked about the supposed 'beef' between the two actresses. 

In a wide ranging chat, Parker also discussed the one time that she'd been fired from a project, on Woody Allen's animated movie, Antz.
