Former Desperate Housewives star Eva Longoria has hit out at Khloe Kardashian for cutting an interview short after she was asked about her sister Kim's daughter North.

The 39-year-old actress can't understand why the 28-year-old reality star refused to discuss anything personal during a live interview last week, when she shares her life on her E! show Keeping Up With the Kardashians.

Speaking to the Confidential on Nova radio programme, Eva said: ''There's definitely things that are off-limits and shouldn't be asked (but) I think it is different for a reality star than it is for an actor.

''An actor goes out and acts and does work, certain things are left to be private.

''Reality stars are kind of living out their lives, that's why they are famous, because of the reality of their lives.''

Despite Khloe's spokesperson confirming the interview was cut short when the topic of North was brought up, Khloe denied that that it happened.

Taking to her Twitter account, Khloe posted: ''Why would I cut an interview short because of North? Get over yourself Sunrise... The call dropped... stop reaching for a story.

''You are so ******* desperate!''
