Rakul Preet Singh is on a cloud nine. After all, 'SPYder' is generating unprecedented buzz.

Since Rakul is a fitness freak herself, did she discuss it with Mahesh Babu on the sets of 'SPYder'? In her latest interview, the hard-working actress says that she and her superstar co-star bonded big -time over the topic of fitness.

The 'Rarandoi Veduka Chuddam' and 'Jaya Janaki Nayaka' damsel is playing a girl named Charlie in the AR Murugadoss-directed, mega-budgeted, spy thriller. The trailer presents her character as a not-so-aware girl. Is she immature? Rakul thinks so. She is somewhat naive and bumbling in the film.

Set to hit the screens on Sept 27, 'SPYder' will release in Telugu and Tamil in a record number of theatres.
