Actress Eva Longoria has a stern message for reality TV stars who don't want to discuss their private lives 'on or off' TV.

Last week, Khloe Kardashian reportedly pulled the plug on a live TV interview when Sunrise host Samantha Armytage asked about her sister Kim's baby North West and general questions about her life, which she refused to answer.

Now, Longoria is making her views clear when asked to comment on Khloe's recent reluctance to open up about her life and family.

Eva, who was recently in Australia for the Melbourne Fashion Festival, told Confidential on Nova radio program:

'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,' the L’Oreal ambassador said.

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

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

Despite living her daily life in front of the E! cameras, the 29-year-old "Keeping Up With The Kardshian" star seem to have gained a desire for privacy since the breakdown of her marriage to basketball player Lamar Odom.

While her Australian representative confirmed to Sunrise that the interview had been terminated following questions about baby North, Khloe however still denied it in a series of scathing tweets.

'Why would I cut an interview short because of North? Get over yourself Sunrise... The call dropped... stop reaching for a story,' she wrote. 'You are so f***ing desperate!'

Do you think celebrities whether reality stars or actors have the right to privacy? Should certain questions be off limits for reality stars?
