We were the first to tell you (see our 10:57 am post), but here's the update. After Sheila Ki Jawani, Katrina Kaif is all set to sizzle on a new item song for Karan Johar's upcoming film 'Agneepath'. The actress will be performing to 'Chikni Chameli' for the Hrithik-Priyanka starrer, scheduled to release on Republic Day next year.Earlier, Katrina did an item song for Farah Khan's 'Tees Maar Khan' and another special song for Salman Khan's 'Bodyguard'.
