Tulisa Contostavlos has been given a dressing down for having parties in her X Factor dressing room with her pals.

According to The Sun, the music show's bosses have clamped down on the 'Young' singer's partying ways after the star continously opened her room to her friends until the early hours of the morning.

"It's just not very professional," a source told the newspaper - also revealing that Tulisa's friends were helping themselves to the minibar.

"When they won't leave it means the security staff are stuck there waiting to lock up," the source added.

The paper has reported that X Factor bosses are keen to cut down on bad behaviour after contestants Rylan Clarke and Lucy Spraggan were banned from the contestants' hotel for their drunken antics earlier this week.
