And the former girlfriend of Twilight co-star Robert Pattinson --who is now rumored to be dating Elvis' granddaughter Riley Keough --wasn't shy about displaying her sexy style for delighted fans and photographers.
Stewart flashed her backside in her designer onesie, featuring a strapless black bodice top and sheer lace pants. While she arrived in frumpy black flats, the star quickly ditched them for spiky- heeled Christian Louboutin shoes displaying the designer's signature red soles.
The wild child actress, who admitted to cheating on Pattinson with her married Snow White and the Huntsman director Rupert Sanders last year, also showed off a new tattoo, a figure 8 on her right wrist.
Stewart, a huge fan of Murad, then sat in the front row of the designer's show, and applauded as the models paraded down the runway. The often surly-looking actress appeared to feel as good as she looked, even cracking a smile at the fashion show!
