BURBANK, Calif. (AP) — Minnie Driver says she's got the bump.

The 38-year-old actress and singer confirmed during an appearance Thursday on NBC's "The Tonight Show With Jay Leno" that she's pregnant with her first child.

Leno joked that she appeared to have gained weight.

"Are you calling me fat? You've noticed my tummy, haven't you?" Driver said.

"Are you pregnant?" Leno replied.

"Yes, I am," she said.

Driver said she loves being pregnant but is frequently sick.

"I don't know why they call it morning sickness," she said. "I am sick morning, noon and night, but it's a fair trade-off."

Driver didn't reveal the name of the father.

A call to her publicists seeking comment wasn't immediately returned yesterday.

Driver stars on the FX cable TV series "The Riches," which premieres Tuesday.
