RACHEL Riley was hotting up the screens during the latest episode of Countdown.
The blonde bombshell looked radiant as she graced screens during the latest episode of the Canal 4 quiz game.
Rachel looked elegant in the dress which featured a floral pattern running across the outfit.
The red and pink floral detailing helped to brighten up the dress and enhanced its darker blue base colour.
Her blonde locks featured simple waves rolling down to her shoulders as she kept one side of it tucked behind her ear.
She completed her stunning look with a splash of simple yet effective make-up and minimal jewellery in order to keep the focus entirely on the impressive outfit.
Rachel was working alongside Trevor who was standing in for regular host Colin Murray as part of a month long series of special episodes to celebrate the 40th anniversary of the programme.
Trevor is one of a number of specially chosen guest hosts who have been given the honour of hosting a week on the show.
