Heather Mills won rave reviews from the judges on the second episode of US TV show Dancing With the Stars after stunning them with a backwards walk over.

Paul McCartney’s estranged wife, wearing a green sequinned catsuit, left the panel temporarily speechless by successfully completing the tricky move as part of a hip-wiggling mambo, reports the Press Association.

They awarded her an impressive 24 out of 30. Combined with her score from last week, that means she is now in fifth place, ahead of the first elimination, which will take place on Tuesday night.

Bruno Tonioli exclaimed: “Beyond any expectation! You were a ‘warp drive’ tonight.”

Choreographer Carrie Ann Inaba was equally amazed, beginning her appraisal by saying: “What in the world?”

She continued: “You did a back walk over. I’m just so blown away by you. The level of difficulty in that routine was far higher than anyone else’s routine tonight and you would think you wouldn’t throw that in but you did and you nailed it.”

Len Goodman said he had been worried the mambo would be too much for Mills, but that it was actually better than her foxtrot last week.

“It was great,” he told the former model.
