Watch: Leona Lewis performs 'Fire Under My Feet' on The 'John Bishop' Show...

As rumours continue to swirl around Simon Cowell's Syco sabotaging her musical comeback, Leona Lewis is taking everything in her stride by promoting her new tune some more.

Le-Le delivered an energetic performance of  latest single 'Fire Under My Feet' during a recent visit to The 'John Bishop' Show this week.

The song has not been getting much radio play, which may have largely contributed to 'Fire' under-performing.

However, it's great that she's been performing the song much more now, though it would have helped had she scheduled her promo a lot earlier than this. I suppose it is what it is at the end of the day.
