"I was back! It was so much fun," she said.

It was the first time she'd been on the show since Johnny Carson banned her nearly 30 years ago, for taking a job hosting a rival late-night show on Fox. The ban continued through Leno's long reign.

INSIDE EDITION caught up with Rivers in Los Angeles, the day after her return to The Tonight Show.
