There was no mistaking who the birthday girl was on Friday night.

With big hair and a razzle dazzle ’em dress, supermodel Rosie Huntington-Whiteley wowed as she partied at The Nice Guy in Los Angeles with fiance Jason Statham, 48.

Rosie, 28, had certainly let her hair down and was lead out of the celebrity hotspot by her Hollywood actor beau before cracking out a few dance moves in the car home.

Birthday girl: Rosie Huntington-Whiteley celebrated her 29th birthday with fiance Jason Statham at The Nice Guy in Hollywood on Friday night

Protective fiance Jason – who proposed to Rosie in January – co-ordinated her footsteps to the car by taking her hand, like a true gentleman.

She put on an extremely leggy display in dainty silver sandals that pulled together a top-to-toe metallic look, which also featured a matching clutch bag.

Her sequinned dress skimmed off high on the thigh, though it was also high on the neckline to emphasise her long and lean figure.

Despite being a natural beauty, the big hair and date night beauty look had taken some time to create at home.

She kept her fans up to date with her regime by shooting behind-the-scenes clips for Instagram, including her useful ‘1-minute Quick & Easy Contour’ video.

Rosie also shared a fun picture of her playfully feeding birthday cake to a male companion inside the party venue.
