Ok, now i guess Madhura is lying, as in one article she is saying that 'when i heard about Ali-Sara's engagement, I just asked her about it, then i dont know what happened between the 2 lovers and i am getting threatening calls from ali' and in another article she is saying that 'i asked Sara to be careful of ali', and sara is also admitting in this article that Madhura said that to Sara. So that means Madhura is going on lying and changing her statements! And if u see from this article itself u can make out how simpler a person Sara is that she dint even say anything against Madhura's comments against her, and she is still maintaining that they are friends. Maybe Madhura dint like Sara telling her to stop interfering in their relationship, thats y she is saying all crap about Sara!
About Ali mentioning that Madhura is not very friendly with anyone, I guess that might be true as she had come to Kya Aap Panchvi Paas Se Tez Ho in the Sara-Parul episode and while everyone were talking very friendlyly to Shah Rukh, she appeared a bit reserved not being too friendly.
Maybe since her role is ending next week, she is trying to gain some attention as she would no longer be a part of India's current top seriel.
Anyways, I dont think Madhura is wrong when she says Ali is a Casanova, but apart from that I think she is cooking up some stuff on her own to gain attention! Thats wat I think, and anyways I dont like her in the seriel also, so glad her role would be ending next week, atleast Sara would be peaceful from her interferance and rude behaviour.
