X Factor favourite Tamera Foster has confessed she's nervous about tonight's show.
It's Disco week on the ITV series this weekend with the nine remaining contestants singing classic club anthems from the 70s, 80s and 90s.
But despite being the bookies' tip to win, Tamera admitted she's worried about her performance.
"I'm a little bit nervous because I don't know the first thing about disco," she said this week. "I need to try and adjust my voice to get into the style"
However her rival Sam Callahan is in his element, saying he's more than a little confident about being able to impress both the judges and viewers with his song.
"I think I'll do alright because I can move and dance," he explained. "My thing is getting up there and getting everyone else up, jumping and having a good time and I think that's something I can do."
