I personally think she has said the correct things ... it is not immature but actually very smartly planned statement. Because if you read it carefully she has said all the things which should make the producer scared and uncomfortable. She has said:
a. She and the co-star are now very uncomfortable (so the production team may not get the best acting results now from them!)
b. She openly said Sony is good, production house is bad
c. She said they have had payment problems from production house
d. She has said that she suspects them of spreading this story for TRPs
e. She has said they have spoilt her mental peace, she is not even safe driving to the shoots (she may turn up late etc and give them headaches!)
I think she has played some very smart cards calculated to make the production house look silly and desperate - and to make them now uncomfortable that they may not now expect full cooperation from her and Apu!
I am sure both she and Apu will now use this silly article about their affair to their advatage ... because the production house is now on the back foot, so the stars can now throw their weight around and act all upset and angry and irritated and non-cooperative! And get whatever they want using a bit of strategic nakhre baazi!
