After the highest-scoring Dancing with the Stars premiere ever, only one person has remained at the top: Katherine Jenkins. The classical singer and her partner Mark Ballas have led the leader board for three weeks running — earning two 10s for her heartfelt waltz in tribute to her late father last week. She will look to four-peat Monday with her paso doble for Rock Week. "It's wild! Never in my life would I think I'd be doing this well and would be getting these marks and comments," Jenkins tells TVGuide.com. "But I'm not concerning myself too much with scores or trying to [maintain a streak]. You can't think about that." See what else the Welsh native has to say about joining the show, the fan reaction and shaking her naughty bits.
