The actress, who dumped cheating hubby Michael Morris for straying with his “Smash” star Katharine McPhee, enjoyed a girls’ night out with Reese Witherspoon and Chelsea Handler at Chanel’s LA book party for Drew Barrymore’s “Find It in Everything” last week.

“Mary was relying on them for support,” said a spy. “They held tight together all night.”
