American rapper Haze published the lyrics for the verse on twitter, saying "Sucks that you guys can't hear it," because the label 'didn't like it'. Haze wrote additional lyrics for Lana Del Rey's cover, but her label (Island) were unwilling to let Del Rey's label (Polydor) release the track.
Lana originally covered the famous 50's song during a H&M advert last year, after she became the new face of the fashion brand's 'LA Noir' collection.
The track also appeared on the Paradise Edition of her debut album, Born To Die.

Earlier this month, a previously unheard track by Lana Del Rey leaked online. 'Beautiful Player' was believed to have been recorded in 2013, and is the second time that this has happened this year - after last month when another new track,'Queen of Disaster', leaked online.
