What price did sultry actor Shveta Salve have to pay for putting in so much of hard work for Sony's Jhalak Dikhhla Jaa? A bruised knee! Recently when Shveta was practicing non-stop on her Rumba number for the upcoming episode, she tripped because of some certain moves and hurt her knee. "It's swollen and my skin has turned blue," she says. But this sassy dancer is still practicing as she puts it, "No pain, no gain" and she attributes her grace to her genes, "I come from the Kolhi family and probably dancing is in my blood!"
