Even when she was the target of Joan Rivers' red carpet zingers, Reese Witherspoon still laughed.

"She was always very nice to me and even when she wasn't I still laughed," the Oscar winner told E! News. "She still made me laugh."

Witherspoon was a fan of the late comedian, who died last Thursday at age 81.

"I love Joan," Witherspoon told E! Toronto International Film Festival.

"It's a hard thing because everyone loved her so much," she said. "But seeing all this wonderful work that she did, how she entertained people for years and years, it just really touched my heart."
