Rock matriarch Sharon Osbourne was left red-faced during a cooking segment on her U.S. daytime show The Talk on Wednesday (05Mar14) after one of her artificial nails fell off while she was helping to make a stuffed steak dish. She only realised the dark red acrylic from her left index finger had gone missing when co-host Julie Chen pointed it out halfway through the piece. The artificial nail was later found after a commercial break.
