N-Dubz singer Tulisa Contostavlos was one of the many artists rumoured to replace Cheryl Cole as an X Factor judge, but it was reported that she was turned down because she couldn’t stop swearing.

She was allegedly invited to a one hour screen test where she apparently used a series of expletives and foul language of all sorts that is not suitable for family friendly television.

However, Tulisa tweeted to her followers that it was all a bunch of  lies and hearsay and that she had never met with the X Factor bunch.

Is this just a cover up for her embarrassment at being turned away because of a potty mouth?

What do you think?
