She's better known for being a homebody than a party girl.
But Holly Willoughby showed that she still knows how to have a good time as she had a rare night out with husband Dan Baldwin at the opening of Viva Forever on Tuesday, vamping it up in a sultry black dress.
Although the blonde TV presenter, who's just been voted the 'world's most desirable woman', ditched her mumsy image for the glamorous outfit, she still decided to change into jeans for the journey home.

While she's best known for wearing tea-dresses and cardigans on the This Morning sofa, Holly was out to prove that she deserves her 'most desirable woman' crown.
The plunging neckline of the off-the-shoulder cocktail dress made the most of her much-discussed curves and showed off more leg than usual, with the hemline sitting a few inches above the knee.

Making sure that the emphasis was on her stand-out dress, Holly wore a simple gold necklace and wadded a simple gold watch and bracelet.
The much-loved presenter went light on the make-up, not wanting to over-power her sultry look and wore her trademark blonde hair in soft waves over her shoulders.

She isn't often spotted out on the town with her producer husband, so Holly clearly relished the opportunity to spend some time with him.
She might have made an effort for her rare night out, but the 31-year-old obviously wanted to get out of her figure-hugging outfit as soon as possible.
Holly changed into a pair of jeans and a black top during the party, opting for comfort over style.
