Tulisa Contostavlos has announced she will release a new single Living Without You.

The song will mark the former X Factor judge and N-Dubz star's first new release in two years. It was originally scheduled to be released in December, but has been brought forward after it was leaked online.

Tulisa tweeted: "My single leaked this afternoon. Someone put it online so we are bringing forward the premiere to RIGHT NOW! Here's the lyric video, enjoy!"

She also thanked her fans for their support, writing: "LOVING all your comments & reactions!! Thank you #LivingWithoutYou."

The dance track has been produced by STL, the team behind her number one single Young.

The 26-year-old singer's last single Sight Of You was released in December 2012.

Last summer she was arrested by police on suspicion of supplying class A drugs after being targeted by The Sun newspaper in an undercover operation. The case went to trial in July but was dismissed as the judge believed prosecution witness Mazher Mahmood had lied to the court.

Tulisa made a guest appearance at the Judges' Houses stage of The X Factor last month, and has been linked to I'm a Celebrity... Get Me Out of Here!
