Missing chemistry!:Raja-Shweta

Shweta Tiwari and her husband Raja Tiwari might look great together as a couple off-screen but as far as their on-screen chemistry is concerned, it isn't sizzling enough. The Nach Baliye 2 choreographers assigned for them have apparently rated the couple five on hundred for their poor on-screen chemistry. While Shweta is a fantastic dancer and has danced in a couple of music videos (remember her dancing in one of Daler Mehendi videos) her husband has never danced in his life and has to start right from scratch.
Considering the dance show is all about a couple's on-screen and off screen chemistry, Shweta is upset as she herself is a graceful dancer and enjoys dancing and her husband is quite the opposite (they have been married for seven years now)

Will someone please tell the talented actor not to get upset as practise always makes a man perfect!
