Eastenders actress and Strictly Come Dancing competitor Louisa Lytton was seen weeping and running from dance rehearsals this week after panicking about her quickstep.

The 17-year-old sobbed to co-stars: “I’m not good enough. I can’t do it.”

A show source said: “Panic set in when Louisa watched the other celebs going through their moves in the dress rehearsal. It was like she had a minibreakdown – it took a while to convince her to come back to the studio.”

The source said show bosses were worried she was going to walk out, adding: “She became convinced she was going to forget her steps and embarrass herself on live TV. The pressure really got to her and the more she watched the others, the more worried she became.

“Eventually it got too much and she left the rehearsal area in floods of tears.

“She had been working hard on perfecting her steps all week. She was feeling confident and when the judges saw her dance in week one they had high hopes for her. But that all just disappeared.”

Fellow competitiors Emma Bunton and Georgina Bouzova finally managed to coax Louisa back into the studio. An insider added: “Louisa’s confidence had taken a real knock. But she picked herself up and got back on her feet like a trooper.”
