Countdown fans flood YouTube with videos of gorgeous boffin Rachel Riley as they reveal her sexiest outfits ever
COUNTDOWN fans have flooded YouTube with videos of gorgeous boffin Rachel Riley and revealed her sexiest outfits ever.
Viewers have been compiling clips of the stunning maths whizz and sharing them online as they count down her best dressed moments.
Rachel has been a huge hit with fans of the show ever since she took over the role from longtime host Carol Vorderman in 2009.
She has won over viewers with her stunning dresses as well as her super-fast mental arithmetic - and they have been posting tribute videos online.
One YouTube compilation is titled "Rachel Riley - Top 5 Shortest Dresses Ever" and another shows her attempting to play mini-golf onset wearing a very skimpy frock.
Another clips shows Rachel wearing a skin-tight flesh coloured dress, which prompted a flood of comments about her bum.
One other shows her putting the letters on the board while wearing a stylish cream coloured gown.
It is captioned: "Amazing booty and sideboob in tight white dress."
It comes after a Countdown clip from 2015 showing Rachel bra-less in a tight, pink dress went viral.
The video has since been circulating online since it resurfaced and has scored around 285,000 hits on YouTube.
Rachel previously became an online hit for another reason - as her boyfriend Pasha Kovalev spelt out VERY rude word on the show.

The Strictly Come Dancing star even managed to draw a chuckle from host Nick Hewer with his answer from the nine-letter jumble MEPHALSUL.
Pasha was taking part in an episode of the game show last Thursday and he left girlfriend Rachel struggling to hold back a fit of giggles when he spelt out the word “phallus”.
There was an awkward silence before Nick said: “Sorry, I was just a bit stunned for a second there!”
It comes just weeks after another saucy incident when the show’s Susie Dent also spelt out a naughty word.
The Dictionary Corner expert left host Nick red-faced when she revealed the naughty saying.
The letters the contestants had to work with were MTHIAEDHS.
But naughty Susie was quick to point out that you could spell “s***head” from those words.
Upon revealing the word she said: “I apologise for this one in advance, it’s in the dictionary.”
She went on: “We’re only saying this because it gets you one letter further, but it’s s***head, I apologise.”
Host Nick then said: “Susie wash your mouth out with soap!”
The camera then flashed to Rachel Riley who had spelt the word out, and was trying not to laugh.
Rachel, who replaced Carol Vorderman in 2009, has often found herself stifling laughter after drawing words like "p**s" and "a**e" in the past.
She has also had to spell out the words "orgasm" and "todgers" during her time on the daytime show.
