Renee Zellweger showed off her rail-thin frame as she left the Sunset Marquis hotel in West Hollywood yesterday.

Renee Zellweger sported a brown checked dress which cinched in at her tiny frame and appeared too big for her.

Her very slender pins were also visible in the short utilitarian frock and the Bridget Jones star made her legs look even longer and slimmer by donning a pair of nude platform peep toe pumps.

Renee Zellweger wore her honey blonde locks piled atop her head in a ballerina bun and toted a crocodile skin handbag.

Despite her gaunt appearance she seemed in good spirits and flashed a smile to photographers before stepping into her red Mini and speeding off.

The actress will soon be preparing to reprise her role as Bridget Jones in a third installation of the comedy saga.

But it is believed that the star will be sporting a fat suit instead of piling on the pounds once again for the film.

She famously gained two stone for the first and second films before dieting back to her usual slim self.

Her co-star Hugh Grant revealed earlier this year that though production has been held up yet again, fans can expect to see yet another love triangle between his character, Daniel Cleaver, Bridget Jones and Mark Darcy.

He told MTV back in April: “I’ve seen some scripts. They haven’t quite hit the nail yet, but they will. They’re working on it.”

Of the love triangle, he said: “Our public demands some more fisticuffs!”

The third film was first announced in August of last year.

Bridesmaids director Paul Feig was originally in talks to helm the film, though the Full Monty’s Peter Cattaneo is now slated to direct.
