“We were friendly,” Portman told Stephen Colbert during a Thursday interview on CBS’s “The Late Show” to promote her new documentary, “Eating Animals.”

Asked by Colbert to elaborate on her relationship with her fellow 37-year-old, Portman hesitated.

“What can I say?” she said with a laugh.

“Anything you want,” Colbert replied, “it’s a free country.”

“I mean, the last days of, maybe. Right?” Portman shot back.

“Unfortunately, there’s not a lot funny to say about someone you were friends with becoming a super villain,” Portman continued. “So, you know … it’s not funny.”

“He said in some interview that the friends he’s lost because of politics, it’s like exfoliating,” Portman said. “I was like, OK — the spa metaphor.”

“So you’re a dead skin cell?” Colbert asked.

The Academy Award winner also weighed in on Kushner’s academic record at the elite Ivy League school.

“I’ve heard he wasn’t that great of a student,” Colbert said, referring to Kushner.

“That is true, yes,” said Portman.

A representative of Kushner did not immediately respond to ITK's request for comment.

A Kushner spokeswoman has previously said that Kushner was “an excellent student in high school and graduated from Harvard with honors.”
