Katherine Heigl has made lots of enemies?

OHMYGOSSIP — Katherine Heigl and her momager Nancy cap­sized her career with their outrageous demands and difficult behavior — it has been claimed. Sources say Hollywood insiders are amused that the actress has come crawling back to TV after a short-lived movie career.

“A lot of people who’ve worked with Katherine say this is karma,” a source said.

“She and her mom treated everyone from producers and directors to script and ward­robe people badly on her way up. So they’re thrilled to see this happening to her now.”

Heigl has signed on to do an NBC pilot about the CIA, but her future appears far from certain.

“Katherine’s wicked ways have come back to haunt her,” said the source. “This pilot may be her last chance for a comeback.”
