Little miss nautical: Super svelte Katherine Jenkins looks striking in backless playsuit.

Katherine Jenkins had a night off from sequins and feathers as she slipped into a striking all-in-one.The Dancing With The Stars beauty celebrated topping the leaderboard again with a visit to West Hollywood venue Mixology 101, striding out in a navy trouser playsuit with sexy crisscross straps.Earlier in the evening, the Welsh songbird had scored an impressive 29 out of a possible 30 for her waltz with partner Mark Ballas performed as part of the Most Memorable Year week on the show.As Katherine ventured out for her evening in La-La-Land, she looked nothing short of breathtaking.

She looked incredibly classy with her hair pinned back and perfectly executed make-up to conceal the fact she had been crying and could potentially fall victim to puffy eye syndrome.

Jenkins, 31, had wept in front of the cameras on the ABC show after selecting her memorable year as 1996, when her father died of lung cancer at the age of 70 – when she was just 15.

The opera star looked ultra feminine despite the slightly androgynous look of the high-neck and billowing flares ensemble, as she showcased her new silhouette after having lost nearly two stone.

She put her rivalry with fellow contestant Maria Menunos to one side, with the girls appearing close as they stepped out arm-in-arm and later left in the same car.

The television presenter, 33, who is also starring on the show, is paired with Derek Hough.

Maria tweeted: ‘What a night!!!!loved Dancing the rumba w/ @derekhough.I feel such a sense of accomplishment w/this dance in particular.so happy!thanks der.’

Katherine is fast proving to be a popular contender of season fourteen, with former DWTS contestant Kirstie Alley tweeting her support last night: ‘@KathJenkins YOU ARE A PHENOMENON !!!!!!!!’ What an extraordinary human being you are!!!! I adore watching your spirit shine…it’s blinding.’

And the dancing hopeful was joined by her No1 fan, with Katherine revealing: ‘With my mum after tonight’s show… So good to have her here in America!’

The shrinking star said she likes to be healthy and the recent weight loss has given her confidence a boost when it comes to wearing risqué dresses – but she is determined not to lose her curves.

Katherine said: ‘I’m burning so much energy now that it’s hard to put the weight back on. But I like to be curvy so I’m trying not to lose any more.

‘But I do want to be healthy, too – there are so many skimpy costumes to wear. That scares me!’
