Pint-sized Hayden looked totally loved-up as she beamed for the cameras alongside boxer boyfriend Wladimir Klitschko, who towered above her.
The Heroes actress made a stylish entrance in an eye-catching sleeveless top, which featured dazzling sequins and cute bows adorning the front.
And as she was attending the Giorgio Armani menswear presentation, it was only fair Hayden gave her prim top a masculine edge with black cigarette pants and aviator sunnies.
A super-slick quiff, bold brows, and a mega-watt smile completed her FROW-ready ensemble.
Top marks, Hayden!
