Renee Zellweger1

Traveling about the country, Renee Zellweger was spotted picking up her BMW from the valet at Los Angeles International Airport on Wednesday (July 15).

Looking to be in high spirits, the "Jerry Maguire" actress strolled outside in a sweater sans undershirt – showing off her belly button before getting into her car.

The sighting comes just as it was announced that Miss Zellweger will be starring as Bridget Jones for the third time – a role in which she has to pack on about 30 pounds.

"Can I just tell you my body is whacked by the time we finish one of those?" Renee told of having to gain so much weight. "It doesn’t know what has happened because it thinks there’s supposed to be a baby and there’s no christening."

As for overeating to accomplish the bulk-up, Zellweger tells, "For two days it’s bliss… Then after a week your glucose levels are going crazy. You’re up and down and all over the place. It doesn’t feel good, and no one wants to hear that, but it’s the truth."
