Leonardo DiCaprio's supermodel girlfriend Bar Refaeli is starring in a new steamy campaign - she appears nude in an online video promotion.

The 24-year-old Israeli model writhes around on a sofa with a sheet barely covering her body parts in a new black and white video set to music and with no dialogue.

The erotic clip was made to promote an art exhibition in her native Israel, reports The Huffington Post.

Just last February, Refaeli hit headlines when she starred as Sports Illustrated's newest covergirl for the magazine's steamy annual swimsuit issue.
