Lana Del Rey teamed up with rapper Smiler back in 2010 when she was probably just known as Lizzie Grant to cover 'Big Spender' by Shirley Bassey, and now the collaboration has surfaced.

Smiler might not be the most exciting rapper around, but it seems he's pretty smart when it comes down to knowing when to release a track.

Have a listen to the track - which is set to appear on his new mixtape All I Know (out February 27th) - below.
