Reese Witherspoon says that she declined an offer to return to “Friends” as Jill Green because she was “too nervous” to film in front of a live studio audience.

“Did you know they asked me back and I said I can’t do it? I was too scared,” Witherspoon said during an interview with “The Morning Show” costar Jennifer Aniston for the Associated Press.

In response, Aniston, who played older sister Rachel Green on NBC’s “Friends,” appeared surprised and jokingly said: “How dare. You got scared?”

Witherspoon went on to say that her nerves got the better of her and she finds shows with live audiences like NBC's "Saturday Night Live," which she hosted once in 2015, "terrifying."

The 43-year-old "Big Little Lies" star also praised Aniston for being "so good in front of a live audience." Witherspoon shared similar compliments during an interview with Natalie Portman for Harper's Bazaar.

"She was so sweet to me," Witherspoon said of meeting Aniston while playing her sibling for two episodes during season six of "Friends."

"I was really nervous, and she was like, 'Oh, my gosh - don't worry about it!'" Witherspoon added. "I marveled at her ability to perform in front of a live audience like that with no nerves. They would change all the lines and she was just so effortlessly affable, bubbly, and sunny. We've been friends ever since."
