Lana Del Rey, A$AP Rocky duet 'Ridin'' surfaces online - listen
'Ridin'' will feature on the rapper's debut album Long Live A$AP, which is due to be released on September 11.
A clip of the track appeared in April as part of The KickDrums' mixtape Follow The Leader, but was pulled so it could feature on A$AP Rocky's studio album.
Del Rey released the video for new single 'National Anthem' yesterday (June 27), which features A$AP Rocky playing former US President John F Kennedy, while Del Rey plays his wife Jackie Kennedy.
Speaking of her rise to fame, Del Rey recently said: "What's scary is when you have your focus on being a writer for ten years, and after that people decide they don't like you.
"That's off-putting, because when you've put all your work into crafting words and melodies, and then people start just thinking about you and judging you as a person that's a little off-putting. But the rest of it isn't scary, it's just sort of different."
