Dani Harmer has been clashing with pro partner Vincent Simone in Strictly Come Dancing 2012 rehearsals this week.
Just five couples remain the competition but only four can continue through to next weekend's final.
This weekend will see the remaining celebs tackle two dances each, and it's proving difficult for the stars.
Dani will be dancing the Argentine Tango with Vincent, and the ballroom pro is keen to make sure they nail his specialist dance.
But Dani confessed training wasn't going all to plan, saying: "It's technically really challenging, it's really hard.
"We've had a few issues when it comes to getting our legs crossed."
She added: "Vincent has been getting very stressed!"
Vincent added: "It could be more of a tangle than a tango.
"I get worried a this point because that is one of my favourite dances and I don't want it to go badly."
