Lara Bingle has become the first casualty on the latest series of Dancing With The Stars after the swimwear model twisted her ankle during a training session on Monday.

Yesterday Bingle, who joked on Sunday night's show that her dance partner needed to be patient with her as her energy levels waxed and waned, tweeted that her physiotherapist had advised her to take four days off after hurting herself.

On Monday she revealed: "Oh NOoooo ... My physio just said I should take 4 days off dancing due to twisting my ankle!" Yesterday she was not taking calls despite being seen strolling in Kings Cross.

The model has been performing well on the dance show where she has been teamed with dance instructor Carmelo Pizzino and finished fifth in the rankings on Sunday night.

But cracks look to be appearing in the couple's professional relationship with Bingle.

A television source said that the reason the relationship has been under pressure in only the second week of the show is that Bingle is working harder than she's worked in her life and the strain has started to show.

In the past fortnight contestants have been working up to seven days a week and training from between 30 hours a week - Bingle's confessed workload - to 50 hours a week, Brynne Edelsten's workload.

Yesterday Bingle looked to have returned to the dance studio, the model tweeting an artistic photo of herself in a dance studio.

"Just me and studio ... " she said ambiguously.

Bingle was runner-up in Channel 9's Dancing On Ice series in 2006 so few are surprised to find that she has emerged as a competent dancer. Her main problem will be being unknown to voters outside Sydney.
