Renee ZellwegerRenee ZellwegerSteady, now.

We all have trouble walking sometimes...

And Renee Zellweger is no exception.

The Hollywood star got a bit carried away at the premiere of her new animation flick, Bee Movie, in London last night.

So giddy with excitement was she, Renee had a little tripsy moment.

Leaving her a tad red-faced.

Still, it's no surprises Renee had trouble walking, given she had to brave a loada English rain as she took to the red rug.

"I'm so wet," Renee told reporters. "My Carolina Herrera dress weighs about six stone."

The star also took time to chat to us about how she kept in shape.

"There's no fitness regime," Renee told Sky Showbiz. "There's just a lifestyle. It involves keeping my sanity if I go to the gym, and working out the weirdness of the day."
