Vanessa Feltz says reheasing the waltz for Strictly Come Dancing this week has made her want to cry.

The broadcaster and journalist has spent the week practising the dance with her partner James Jordan, for a performance on the BBC show tomorrow night.

She said: “The waltz is about love and loss. Just like everyone else, I have been through some tough times.

“It moves me very deeply and I find myself sobbing at the thought of it.”

Ms Feltz, 51, will perform the dance to Whitney Houston’s emotional ballad, “Run By You”.

Strictly's other Jewish contestant Rachel Riley's concerns this week were more practical. The Countdown co-presenter, who will dance the salsa with partner Pasha Kovalev to Daft Punk’s “Get Lucky”, was worried that she would forget the steps.

“I really hope my two left feet don't let me down on the night,” said the 27-year-old maths-whizz.

“I'm going to leave tomboy sporty Rachel at home, and bring elegant, glamorous Rachel to the dance floor.”

Last week’s opening performance for the show’s series saw the two celebrities poles apart on the competition judging board. Ms Feltz came third from last with only 19 out of a total 40 marks, while Ms Riley came in sixth place with 27 points.

Out of the 15 celebrities partaking in this year’s eleventh SCD series, model Abbey Clancey came out on top with 32 points and Dave Myers received the lowest mark, 16 out of 40.
