Amy Winehouse missed out on the chance to see her precious Blake Incarcerated yesterday, when she showed up late for a scheduled prison visit.

She arrived at Pentonville Prison with a red heart with Blake’s name in the middle of it, pinned onto her blouse. She was turned away at the gates because she missed her appointment.

A source tells the Sun, “Blake is getting really wound up by Amy. Her visits are less and less frequent – and when she does visit, she is late. “He has told Amy he wants a divorce. Part of that is about getting her to visit. But he’s closer to going through with his threat.”

Amy should get/stay clean and hook up with Mark Ronson.
