Lisa Kudrow spills never-revealed secret about 'Friends'

Lisa Kudrow has spilled a never-revealed secret about hit US comedy series 'Friends' saying that the show was actually considered racy 20 years ago.

The 51-years-old actress asserted that when they were shooting the pilot episode, the network got really nervous because the character Monica sleeps with a guy on the first date, ABC News reported.

Whilst talking about the show on Jimmy Kimmel Live, Kudrow continued that they were really nervous as people may think it was "slutty".

Kudrow added that the network even prepared a survey for audience members with questions about how the situation involving Monica and the salesman made them feel.
