X Factor finalist Sean Smith will perform on his first live X Factor show next week along with his sister Sarah as part of the group Same Difference.

But Sean has admitted that he intended to audition as a solo artist this year, and was peeved by his sister suddenly teaming up with him at the auditions.

“Sarah had only come along to support me in auditions and suddenly we were duetting. I was a bit peeved,” Sean told The People. “I felt she’d stolen my thunder but I’m happy about it now.”

“We used to tear each other’s hair out as kids. I hated it when she decided she wanted to sing,” he admitted. “I was meant to be the singer. I always beat her in competitions. This is the first time we’ve done it together. But we’ve got to make it work.”
