The 'Blow' singer's latest song has leaked online ahead of her second album's release in 2012.

A new track from Ke$ha has leaked online and sees the 'Tik Tok' singer heading in a more pop-rock direction than her previous dance-oriented sound.

'U Better Know' is reportedly a demo recorded by the singer recently, although it is unknown whether the song will feature on her second album next year.

The 'Blow' singer has previously saysshe is taking her time on the follow-up to 2010 debut album 'Animal' and expects it to be released around May 2012.

Ke$ha released a repackaged edition of  'Animal' along with special EP' Cannibal' in November 2010 following her chart success.

The singer, who penned Britney Spears' mega-hit 'Till The World Ends', collaborated with the 'Femme Fatale' star as well as rapper Nicki Minaj on a tour remix of the single earlier this year.
