RACHEL Riley wowed Countdown fans as she looked stunning on the Channel 4 game show.
The TV personality looked radiant in a unique looking dress on the show.
Rachel's low-cut offering was mostly red with a white patterned detailing as is hung around her upper arms and down to the ground.
The bold outfit however featured a block of blue on the chest area complete with a number of white stars.
Rachel looked sensational in the striking number commanding all the attention on the show.

She kept her make-up simple as she let her blonde locks fall loosely around her shoulders.
It comes after Rachel recently had a pop at her co-star Susie Dent with a thinly-veiled comment.
Host Colin Murray said: Is there a repetitive thing about Countdown that after all these years...annoys you a bit?"
Rachel, who has been in charge of the letters and numbers since January 2009, replied: "I mean obviously ignoring Susie..."
She immediately laughed to show she was joking, while Dictionary Corner star Susie shoulders lifted in a chuckle as she smiled and said nothing.
Rachel continued: "No I love this show, if I didn't like repetitive jobs I wouldn't be very good on here.
"And even the Countdown theme tune I think is great."
She then dropped a bombshell by saying to Colin: "Before your time, before my time, someone interviewed for your job but but they requested that we changed the Countdown theme tune."
