Offlate, Kajal Agarwal is getting very busier with continuous projects in hand and is implementing 'Plan B' when she is busy. If the actress can't be a part of particular project, then she is immediately re-routing them to her sexy sister Nisha Agarwal. For the same reason, Kajal is roping her sister into all those ad-campaigns she is part of, to shake alongside her. For now, there is no fee that is to be given to her sister Nisha when she shares the screen along with her sister. For industry experts, this looks like a 'Pay One – Get Two' offer Kajal has undertook to promote her successor. Looks funny but true, watch Chennai Shopping Mall and other Tamil ads for clarity!
