It seems the Bollywood fever has caught up milky beauty Tamanna these days. Recently, the pretty lass has turned down the offer to act opposite Super Star Mahesh Babu in his new movie under the direction of Sukumar. Reportedly, Tamanna has chosen Bollywood heartthrob Ranbir Kapoor over Mahesh Babu, says production hands. The makers of Mahesh Babu's new film have asked bulk dates of Tamanna for 80-90 days and it's unlikely for her to sign this Mahesh starer at this stage, says Tamanna's father Santosh Bhatia. He also added that Tamanna will foray into Bollywood this year without revealing any details in particular. Tamanna is all set to make her debut in Bollywood opposite Ranbir Kapoor in producer Vashu Bhagnani's film.
