Couple of months ago, a newspaper daily reported that the actress’s friends complain about her being so busy that she cannot find time to hangout with them. She apologized on twitter saying that she is busy shooting three films that included – Dabangg 2 and Joker. Sonakshi’s next venture will be Shirish Kunder’s Joker. This will be Akki – Sona’s second movie together. Akshay and Sonakshi share a strong bond of friendship and people from the sets on Joker swear by their chemistry. A source from the sets said, “Sonakshi and Akshay have a lot of fun shooting on the sets and have become friends.” Her recent film with the Khiladi proved to be a success and she has two more films lined up with him — Shirish Kunder’s Joker and Milan Luthria’s forthcoming film have Sona paired with Akki. Seems that Katrina Kaif is no more AK’s lucky charm, it’s Sona for him now. Akshay stopped taking projects with Katrina Kaif after their chemistry flopped in last few movies at box – office. Akshay who did near about half a dozen movies with Katrina Kaif now prefers shooting with Sonakshi Sinha. While Katrina Kaif was considered a lucky charm for Akshay, we wonder if Sonakshi can replace her. Only time will prove how long the Sona – Akki chemistry woo the audience.
