Tulisa responds to sex tape scandal - ITN

X Factor judge Tulisa Contostavlos said she felt "devastated" after a private video of her was leaked online.

The N-Dubz star admitted, in a video posted on YouTube, that she is the girl in a sex tape which has been circulating on the internet.

During her video confession, Tulisa identifies the man as ex-boyfriend MC Ultra, dispelling rumours on Twitter that the film was made with bandmate and former-boyfriend Fazer.

The singer explains she feels like she has been betrayed by someone she "loved deeply".

Tulisa apologised to her fans for any offence caused, but said she does not believe she is to blame.
