Why is Sonakshi Sinha keeping away from 'Koffee with Karan'?

Despite being unabashedly vocal about her opinions, Sonakshi Sinha intentionally kept herself from appearing on Karan Johar's chat show. The reason however has nothing to do with her wanting to evade awkward questions.

Apparently, host Karan Johar had allowed Sona to decide who she wanted to partner with, but the actress can't think of anyone. She considered her 'Force 2' co-star, John Abraham, but given that the film has released, that option too is now unavailable. Suggestions anyone?
