Glee actress Jenna Ushkowitz and moviemaker Ryan Kavanaugh are among the stars who have given blood for a bizarre piece of art by controversial photographer Tyler Shields.
The snapper has rounded up 20 celebrities, also including TV star Shannon Collis and producer Brent Bolthouse, for the piece, which he will unveil at his Life Is Not a Fairytale exhibit in Los Angeles next month (May11).
He tells the New York Daily News, "We drew vials and vials of blood from people. I have a refrigerator full of blood right now in my bedroom, which is hilarious.
"It's all mixed together. You won't know whose (blood) is where."
But Shields' request for blood wasn't accepted by everybody he asked - Star Trek actor Zachary Quinto turned down the project.
Shields adds, "Zachary said, 'I might be weird about needles'. (He was too) squeamish."
The photographer hit headlines last year (10) after smearing Lindsay Lohan with fake blood for a photoshoot.
