Samantha seems to believe Pooja mocked her deliberately

Samantha seems to believe Pooja mocked her deliberately
A post on Pooja Hegde's Instagram handle on Wednesday night said that Samantha Akkineni doesn't look pretty at all.  As per the 'Maharshi' actress, it was the act of miscreants who hacked her account.  
It doesn't matter what Samantha's fans are thinking about this.  As fanboys and fangirls, they would be naturally inclined to disbelieve Pooja's claim.  What may be of interest is what Samantha seems to be believing.
If the 'Majili' actress' latest Twitter posts are anything to go by, she seems to believe that Pooja made fun of her deliberately.  The 'Oh Baby' actress posted a pic without make-up and flashed the 'V' sign.  Later in the day, she retweeted producer Mahesh Koneru's comment: "Kill them with your success and bury them with your pretty smile".  
In the meantime, playback singer and Samantha's long-time friend Chinmayi indirectly took on Pooja.  She made a series of pro-Samantha tweets, showing her as a gem of a human being.  Chinmayi tweeted, "I have always and forever spoken out about social media bullying.  ‘Don’t be a bully/Don’t abuse’ is a concept maladjusted people don't get.  Sam is a truly beautiful human being. Anyone who has been involved with and knows about Pratyusha Org and her work would know. End." 
The question is: What might have caused a rift between the Samantha-Pooja duo?  Might it be because of a film offer?
