The English singer-songwriter - real name Natasha Khan - is gearing up to release her third LP titled The Haunted Man on October 15.
"You're the train that crashed my heart/ You're the glitter in the dark/ Oh, Laura/ You're more than a superstar," sings Khan in the piano ballad.
'Laura' will be available as an instant download to fans who pre-order The Haunted Man on iTunes from midnight on Tuesday morning (July 24).
The upcoming album's artwork was shot by photographer Ryan McGinley.
On the cover, Khan appears nude while carrying an undressed man on her shoulders.
Bats For Lashes previously announced her first UK gig in a year and will go on tour in support of her new album.
