Irrespective of the religion, caste, social status etc. almost everyone in the country is celebrating Raksha Bandhan aka Rakhi festival today.Several celebrities are posting their Rakhi pictures on social media to let the world know about their darling siblings. We brought you the cutest Raksha Bandhan pic that you can see today. In tollywood, who could be the cutest brother-sister duo other than Gautham-Sitara, the darling children of super star Mahesh Babu.In the pics, cute Sitara is seen tying rakhi to Gautham, of course with the guidance of doting mom Namrata. She is also seen offering a sweet dish, presumably prepared by Namrata, to Gautand and taking his blessings. The duo looks to be enjoying the moment with a blushing expression on Gautham's face.
