Lana Del Rey has pleaded for help after her family’s belongings were stolen over the Christmas period.
The US singer, 34, wrote on Twitter: “This week, family mementos including my sisters entire retrospective were taken.”
She offered a reward for the return of the valuables.
“I’d love to encourage whoever took it to please consider sending any of the scans of her previous work back to us for a no questions asked reward,” she wrote.
“The work we lost can’t be reproduced and exists nowhere but where it was.”
Fans flooded the star’s Twitter page with supportive messages.
“I pray they find their heart and give back the work,” one fan wrote.
Others branded the theft “disgusting” and “messed up”.
Del Rey’s younger sister, Chuck Grant, is a photographer whose images have featured in publications including Rolling Stone, Playboy and Fader.
She regularly posts images of her famous sister and the pair have worked together on visuals for Del Rey’s music.
