Kajal Agarwal was the reason Why Nisha Agarwal rejected Jilla ?

Ever since Kajal Agarwal was roped into play the lead role in Jilla, there were several rumors linking the other agarwal 'Nisha' also with the same project . She did deny it saying it was just a rumor and she wasn't approached at all. 
However sources in kollywood have conjured up with two different rumors. 

Rumor 1 :
Sources reveal Nisha Agarwal's name popped up only because Kajal Agarwal had recommened her in the first place , but Kajal Agarwal  hasn't taken these rumors well , She has reportedly made it clear that she would never recommend her sister like that. Kajal added that  "I strongly believe that no one can sustain because of recommendation. Only their talent and hard work will prove success."

Rumor 2 :
There is another side to story which reveals that Kajal's younger sister Nisha was indeed offered with a chance to pair up against Mahat in 'Jilla' but it was Kajal who stepped in and rejected the offer for Nisha, citing it was too small role for her. Kajal has reportedly said "I do not want my sister to do such a small role , yes maybe her first movie 'Ishtam' did not do that well , even i my debut venture wasn't a big success but i waited patiently for my chance so will my sister".
