Sneha's Replacement

In this week's promo I thought I saw Marisha dancing. Can someone confirm if it was actually her? So is she Sneha's replacement for the week? If she is it is good news. I was seriously worried that Sneha's replacement wouldn't be good enough for Ritwik. But I totally love Marisha and love what she did with Chang last season.

P.S.: I THINK it was Marisha, might be mistaken because I saw the promo only once and there she is shown for fraction of a second

P.P.S.: I know I just mentioned Chang, a past season contestant, which I am not supposed to do. But that is just to give context to Marisha and not bring in comparisons.

Oh well I am not comparing the two. I like Sneha. I just like Marisha too and said was disappointed when she wasn't in the season. She could have been in place of someone else, not Sneha specifically.
