Looks like Enthiran actress, Aishwarya Rai, is all set for a big-screen comeback after the child birth. It is heard that the actress might make a big comeback with an item song in ace Bollywood director Sanjay Leela Bhansali's Ram Leela, which stars Deepika Padukone and Ranveer Singh in the lead. And though nothing is finalised yet, she is considering the offer seriously, sources says.
