X Factor: The Band viewers notice odd Leona Lewis habit during final

X Factor: The Band held it's big final on ITV tonight.

The show sees judges Simon Cowell, Nicole Scherzinger and Leona Lewis help pick the next new big pop group.

Battling it out for a recording contract tonight was girl group Real Like You and boy band Unwritten Rule.

However, viewers were distracted from the pop battle by something judge Leona, 34, kept saying.

Many fans of the show noticed that the former X Factor user wouldn't stop using the word 'energy'.

One commented on Twitter: "Someone have a quiet word with Leona, and let her know there's no energy."

While another added: "Leona keeps talking about 'the energy' in #xfactortheband."

A third asked: "Is Leona sponsored by British gas? She keeps talking about the "energy".

Despite the complaints, others commented that Leona looked "beautiful" in her nude illusion dress.

Fellow judge Nicole Scherzinger also wowed in a plunging black dress on the show tonight, which got fans talking.

One commented: "Nicole Scherzinger is looking so beautiful tonight! She literally slays every outfit she wears and her makeup is amazing."

While another added: "Nicole is not leaving much to the imagination tonight."

A third gushed: "You’re looking smoking hot as per queen."

Tonight's winners of The X Factor: The Band will receive a recording contract at Cowell's record label, Syco.

This evening's final will see X Factor 2018 winner Dalton Harris return to give a performance.

We can't wait to see which band ends up taking the crown.
