It is known news that Samantha has been going ga ga over Mahesh Babu. It is also heard that during shooting time Samantha was moving ‘closely’ to Mahesh and this whiff was given to Namratha. The unit members of ‘Dhookudu’ reveal that Namratha gave a special class to Samantha and gave her a strict warning.Just like the way she fell flat for Mahesh during the time of ‘Vamsi’, Namratha is aware that there is the danger of other heroines falling flat for her hubby. That’s why it is heard that she keeps an eye on his leading ladies and if she senses anyone getting close, she gives warning to them in her own style. Buzz is that this is one reason why any heroine acts only once with Mahesh Babu and Namratha takes special precaution on that. Sometime back, there was news that Namratha gave a similar warning to Trisha. Now it looks like this is the turn of Samantha. Poor Samantha!!
