Today, I dished with City TV about about Kristen Stewart's first public appearance at the Toronto International Film Festival after speculation that she cheated on Robert Pattinson.

I must admit, sometimes it's quite a relaxing break from my hectic schedule as a psychotherapist and relationship expert to answer questions on celebrity relationships - and I quite enjoy engaging in all the gossip!

Ultimately, infidelity affects many of us - about 22% of married men and 15% of married women cheat. Many of the couples I visit in private practice say that their relationships are never the same after cheating.

I certainly think that being in the movie industry has probably changed the game for K-Patz...a high pressure environment and no time with your partner can lead to massive problems! That is, in fact, if their relationship is even real to begin with and not a massive PR stunt.

What are your thoughts?
