Lauren Smith, 19, did an acoustic rock version of Kanye West & Estelle’s “American Boy” on X Factor UK 2012 Saturday night.

After her performance Tulisa Contostavlos raved, “I think we found ourselves a recording artist. It was brilliant I loved it.”

Melanie Brown wasn’t quite so positive, “I have a pet Peeve when people close their eyes throughout the whole song.”

Louis Walsh said, “I’m not sure you’re right for this show though?”

Contostavlos answered back, “How many times do you say we’re looking for a recording artist…we’ve found one?”

He said, “How do you know?”

But Tulisa wasn’t taking his attitude lying down and blasted, “What was your last act? Jedward?”

Gary Barlow brought things back to the competition and told Smith, “Lauren I really enjoyed you. It’s a yes from me.”

Mel added, “I didn’t love it but I liked it. You are interesting, so it’s a yes from me!”

Louis mused, “I’m on the fence but I’m going to say yes.”

But Tulisa wasn’t letting it go and continued ranting at Lou Lou, saying, “Don’t give me all that selling millions of records! That was years ago! When were Westlife number one? Because I was last week.”
