Why Aamir Khan bought a sari for Anushka

Aamir Khan himself has confirmed the news. He went to Benaras and baught a beautiful Benarasi sari. It was an upmarket sari shop and the sari was beautiful and costly as well. But this sari was not for her wife Kiran Rao. Then for whom was this sari? It was for his 'PK' co-star Anushka Sharma. There are wild guesses why Anushka got this special gift from Aamir. Is it an indication that Anushka is planning her marriage with her beau Virat Kohli. Or was Aamir teasing her. Or was it another marketing strategy of Aamir Khan. Or was it pure love, a friend gifting a sari to his friend? You are free to guess.
