Renee Zellweger what have you done to your face?

Bridget actress looks utterly unrecognisable as she steps out with her boyfriend in LA

She's well known for transforming her appearance for movie roles.

But off-screen Renee Zellweger, 45, displayed an astonishingly different look at ELLE's 21st annual Women In Hollywood Awards at the Four Seasons Hotel in California on Monday.

The Jerry Maguire actress looked almost unrecognisable with her super line-free forehead, altered brow and suspiciously puffy face, although she has never admitted to getting surgery.  

She wore her blonde hair in a wispy side-parting, and kept her makeup natural, opting for a light touch of mascara and a slick of pink lipgloss.  

Her choice of dress was a winning look, a black knee-length frock with sweetheart neckline and a sheer embroidered back and sleeves.
