The blonde presented the letters and numbers as she usually does on the Channel 4 favourite.
Although it wasn’t long before she was handed a ‘DUI’.
Don’t worry though, the 31-year-old wasn’t caught driving under the influence.
Instead, it was just the luck of the draw during a letters round.
Pasha Kovalev’s other half laughed off the incident, seemingly grateful it was rather more tame than a Rachel Riley wardrobe malfunction classic.
And she seemed to have recovered from an incident earlier in the week which left her promising not to touch Nick Hewer’s nuts.
As yesterday’s champ Steve Anderson asked for letters, the first three to pop up were D, U and I.
Realising what had happened, Rachel could be seen giggling to herself, though it was nothing like that time she spelled out “squirter”.
The brainiac slipped into a skater-style minidress for today’s episode.
It featured a bright pink top section, cropped at the sleeves to show off Rachel’s slim arms.
The tight-fitted material clung to the mathematician’s body, following her curves incredibly well.
The skirt was black with a giant white star placed on the side, drawing attention to Rachel’s hip.
Unlike Rachel’s usual taste for figure-hugging frocks, today’s ensemble didn’t really show off her award winning rear.
Just like her Countdown predecessor Carol Vorderman before her, Rachel was given the title Rear of the Year.
Time will tell whether or not she will match Carol’s record of winning it for a second time.
Countdown airs weekdays at 2.10pm on Channel 4.
