The lady in white that's not Sridevi but its...

 ...should be obvious to Sridevi fans but comment below, who is this pretty lady in white? 

UPDATE: As people commented on Twitter, yes, its Sreelatha, Sridevi's only sister. Who did a shoot with... I'm guessing Gautam Rajadhyaksha. The soft lighting, the elegance... its very Gautam da style. 

Below, rare pic of Sridevi's aunt and Sridevi's younger sister Sreelatha.
