Jessica Simpson Reveals New Sitcom Based on Her Life

Jessica Simpson talks with Jay Leno about her upcoming sitcom and her surprise pregnancy and when she will get married. INSIDE EDITION has the details.

Wearing a stomach-hugging leopard print dress, a very pregnant Jessica Simpson rubbed her baby bump on Leno last night.

"I'm pregnant again," said Simpson.

Simpson, who's due this summer, told Leno her second pregnancy wasn't planned.

"It was kind of like a one night stand and it happened all over again," she said.

So, will she and her fiance of two years, Eric Johnson, ever get married?

"We've had two different wedding dates but he keeps knocking me up," said Simpson.

She also revealed that later this year she'll be starring in her own sitcom for NBC. She's playing herself, sort of, like comedy icon Lucille Ball. Leno asked what the sitcom is about, to which Simpson replied, "It's loosely based on my life."
