COUNTDOWN'S Rachel Riley has stunned fans as she announced a career shake-up in a glam Instagram video.
The 35-year-old has been part of the Channel 4 show since 2009 and currently co-hosts alongside Anne Robinson, who joined the show last month.
As well as working on the main Countdown show, Rachel also appears on spin-off 8 Out of 10 Cats Does Countdown, which she juggles alongside her parenting duties to daughter Maven, 19 months.
Despite her busy life, Rachel has still found the time to add another string to her bow, and took to Instagram this week to reveal her latest project.
Looking glam in a colourful top and bright lipstick, Rachel revealed: "I am very excited to announce that I have written a book.
"It's called At Sixes and Sevens and it's a maths book for adults who lack a little bit of confidence in the maths department and need an extra hand."
"EVEN VEJAZZLES"
"I will be taking you by the hand and leading you every step of the way. It's a fun maths book, so there's more references to football, cocktails and even vejazzles than you might expect."
She concluded: "It's out at the end of October and I hope you might get something from it."
Rachel, who is married to former Strictly Come Dancing professional Pasha Kovalev, was immediately congratulated on her new book by her followers.
