Lana Del Ray leaked demo track says Lady Gaga 'sucks'

Lana Del Rey has appeared to slam Lady Gaga in a leaked track posted online.

The 'Born to Die' hitmaker seems to hit out at her friend, referring to her as Stefani - the 'Paparazzi' singer's real name - in the song, 'So Legit', which is believed to have been recorded in 2009 when Gaga released hit tune 'Bad Romance' and Lana was still trying to make a name for herself in the industry.
