Dancing With The Stars: Katherine Jenkins Beats All Comers In Week 2, Including Martina Navratilova (PHOTOS, VIDEO)

Katherine Jenkins wowed the judges in her Dancing With the Stars debut last week, and she continued her winning streak this week, showing a much more sultry side.

The popular Welsh soprano took to the floor in a shimminering little black and pink number, and performed a frisky jive with her dancing partner Mark Ballas.

Judges were impressed, giving her 26 out of a possible 30, which took her to the top of the scoreboard for a second time.

Other contestants weren't so successful, with Martina Navratilova, Melissa Gilbert, Gavin DeGraw and Gladys Knight all finding themselves struggling not to be eliminated in tonight's send-off, when one pair when will receive their marching orders.

Judge Bruno Tunioli told tennis star Martina, "I think that serve went into the net."

But it wasn't all bad for Martina. 30 years after she first walked onto Centre Court at Wimbledon, she proved she is still sporting an impressive set of abs, which she displayed along with a washboard stomach and arms that could still carry lorries. Lucky for Katherine Jenkins, this is a dancing comp, and not anything more gladiatorial.
