Countdown’s Rachel Riley dazzles in low-cut pink dress on Channel 4 show

COUNTDOWN'S Rachel Riley dazzled in a low-cut pink dress on the Channel 4 show.

Rachel, 37, was back co-hosting a new series of Countdown alongside Colin Murray, following last week's Champion of Champions episodes.

Rachel looked amazing, wearing a raspberry pink dress which featured a sweetheart neckline and a A-line short skirt.

The math whizz showed off her slim legs in in a pair of high heels and had her blonde hair loose around her shoulders.

The new series comes a couple of weeks after it was officially confirmed that Colin had been made the permanent host of Countdown.

Colin, 45, had been the temporary host since Anne Robinson quit in May last year.

Despite a break in proceedings when the show was hosted by a series of guest stars to celebrate its 40th birthday in November, Colin has been front and centre alongside co-star Rachel.

Earlier this month on Steph's Packed Lunch, it was revealed who would be Countdown's new main host, and it turned out to be...Colin.

He said of his official appointment: "It is pretty surreal, to have been in Dictionary Corner was amazing and then to be the 'caretaker' for the last six months. It's never stopped being surreal."

Speaking about how he used to watch it as a kid, he said: "It was cheeky, it was irreverent, I loved it.

"I get to see it into its fifth decade, being honest I think it's like a football team that used to win trophies and I want it to win trophies again.

"We want it to really thrive, return it to the days when it used to win everything in daytime."

Countdown airs weekdays at 2.10pm on Channel 4.
