Jessica Simpson is NOT Having Twins

Jessica Simpson is not having twins.

During an appearance on The Tonight Show With Jay Leno Monday, Simpson claimed the rumors are false.

“No, it’s not twins,” Simpson said. “I know it looks like it.”

When Leno said Simpson looked like she might give birth any minute, she replied:

“Not quite yet. We have some time.”

The reality star also admitted she’s nervous about giving birth.

“Labor is really going to hurt,” she told Leno. “I have so much respect for my mom and all the women across the world.”
