Lady Gaga Boyfriend Writing Weight-Loss Manual

It pays to have partners in high places, Lady Gaga’s bartender beau — Luc Carl — has landed a book deal based on his blog, The Drunk Diet.

The manual will be “a real shot of hope for all those sad, pudgy little rock stars out there looking to change their lives,” according to St. Martins Press, who will publish the book later this year. Once 40 pounds overweight thanks to his “Whiskey and 5 AM Cheeseburgers” Lifestyle, the manager of Lower East Side rock bar St. Jerome now sports a lanky frame with arms like a bodybuilder. He promises to share the secret to his weight-loss success in the “greatest fucking diet book of all time.”
