Leona 'worried about album failure'

Leona Lewis is reportedly worried that her next album will be a failure.

The X Factor winner is said to be working hard on her upcoming record Echo to stop it "bombing" in the charts.

"Leona knows she's going to have to work harder with Echo to equal, never mind better, the success of Spirit," a source told Look magazine. "She wouldn't want to be a one-album wonder."

The insider also claimed that Lewis is anxious that she has lost her UK fanbase after spending time in America.

"There are plenty of reality TV stars who've been successful with their first album but bombed with their second," they explained.

"The problem is that when Leona first appeared, there was no-one else like her. But things are different now. She has some serious competition and it's preoccupying her entirely. It's as if she can't think of anything else.

"I think this fixation with Alex [Burke] and JLS is fuelling her obsession to make Echo a massive hit. She must feel like she has a huge mountain to climb to achieve the success she did three years ago."
