Lady GaGa lies naked in the arms of a mystery man in the promo video for her forthcoming tour with Kanye West.

The provocative clip was posted on West's blog yesterday under the title: “What Happened to All the Rock Stars? The Fame Killed Them!”

Lady GaGa appears in slow motion in the video, before the words Fame Kills, which is the name of the tour, appears on the screen.

The Fame Kills tour is due to kick off in Phoenix on November 10 before calling at venues across the US.

Both artists are sharing equal-billing on the jaunt, which Lady Gaga said recently would be “one of the most groundbreaking moments in touring history”.
