X Factor 2012 judges: Tulisa acting the diva on set?

Tulisa Contostavlos

X Factor 2012 judge Tulisa Contostavlos is reportedly becoming a bit of a handful on the set of the new series.

Tulisa and her fellow panelists have already filmed the auditions and bootcamp stages of the show, which are due to begin airing later this month.

It's her second year on the show, and after making history by guiding a group to win last December it seems the N-Dubz star has become a lot more confident behind the scenes!

Insiders claim that the 24-year-old has been bossing staff around as much as even X Factor boss Simon Cowell does

"Tulisa has always worn her heart on her sleeve, but lately she's taken it too far. Behaviour which used to be indulged is wearing seriously thin now," one source told Reveal magazine this week. "You'd think she was Simon Cowell the way she throws her weight around."

Her fellow judges meanwhile are said to simply be either ignoring or laughing at her behaviour.

The source claimed: "Gary Barlow tends to ignore her, and Louis Walsh finds the whole situation hilarious."

However the supposed insider warned: "But Tulisa had better hope for good ratings, because if things don't work out on this year's show, there won't be many people sticking up for her."
