Zellweger, Too Sexy For Her Shirt

Yes.  It was hot in L.A. yesterday.  While most people would deal with the heat by forgoing a jacket, Renee Zellweger's solution was to forgo an undershirt.

We spotted the star (and her navel) retrieving her BMW from the valet after landing at LAX.  Renee's reading material?  Fred Kaplan's 1959: The Year The World Changed.

Have you heard they're tossing together a third Bridget Jones movie?  Does this mean Renee will be going on a strict cheese-only diet soon?
