The X Factor: 12 picture teasers for Sunday's episode 8

It's the second weekend of The X Factor's Wembley Arena auditions and the pressure is on. Singing in a closed room and singing in front of an audience are two very different things, and a bad reaction from the crowd could mean the end of the road for the acts.

Ahead of Sunday night's show, here are 12 picture teasers.

1. Returning singer Tom Mann plays an original song, but Simon's not impressed.

2. Ten Senah turned up at her first audition drunk. The 24-year-old from London, tries to redeem herself by singing 'Mama Knows Best', but will it be enough?

3. 30-year-old DJ Michael Marouli leaves the stage and performs in the crowd for his audition.

4. Simon loved Lola Saunders' first audition, but will she be able to top it in front of an audience?

5. Leah Kennedy sings 'It Will Rain' by Bruno Mars.

6. Jordan Morris hopes to wow the judges with his version of John Legend's 'All of Me'.

7. Janet Grogan breezed through the closed-room auditions, so the judges are expecting big things from her.

8. Jake Sims takes on 'When The Sun Goes Down' by the Arctic Monkeys.

9. Returning singer Jake Quickenden got through to the Judges' Houses stage in 2012, but will he make it this time?

10. After her son filled in her application for the show, Helen Fulthorpe has more than just the judges to impress.

11. US Marine Charlie Martinez takes on One Direction for tonight's audition.

12. Louis tells Charlie Jones his performance is better than the original. Is he another dark horse in the competition?

The X Factor airs tonight (Sunday 21) at 8pm on ITV.
