Lana Del Rey has revealed she sang at Kim Kardashian and Kanye West's pre-wedding party at the Palace of Versailles near Paris last Friday for free.

The 27-year-old Summertime Sadness songstress has hit back at claims she was paid $2.8 million to perform three songs at the couple's lavish party at the Palace of Versailles, last Friday (May 23), on the eve of their wedding in Florence, Italy.

Speaking to Del Rey said: ''I would never let a friend pay me to sing at a wedding, that would be crazy.''

When asked how much her fee would be to sing at a normal wedding she said: "I'll do it for free like I did this one!''

The couple asked the star to entertain their guests after Kanye, hired an orchestra to perform her hit Young and Beautiful when he proposed to the Keeping Up with the Kardashians star on her 33rd birthday last October.
