Countdown presenter Rachel Riley appeared on tonight’s instalment of Celebrity Gogglebox alongside partner Strictly Come Dancing professional Pasha Kovalev.
During their time on the Gogglebox sofa Rachel and Pasha sat down to watch quiz show The Family Brain Games hosted by Dara O Briain.
The show pitted two families against each other to see which one would be crowned the cleverest and after a number of different rounds including a memory test they were faced with a maths problem.
After being given two numbers they were given a larger number they had to achieve similar to the maths equation which features on Countdown.
However viewers weren’t impressed when the pregnant star failed to guess the answer and other celebrities did.
One viewer said: “@RachelRileyRR come on Rachel I thought you would get maths sums correctly #CelebrityGogglebox.”
Another added: “Rachel showing off her math skills lol. #FamilyBrainGames #CelebrityGogglebox.”
“Haha Rachel Riley got the maths question wrong! Vorders would have got it #CelebrityGogglebox #BabyBrain,” added a third.
“Wow the maths wizz Rachel didn’t even get it #CelebrityGogglebox,” remarked another.
