Rachel Riley, 33, has been in a relationship with Strictly Come Dancing professional Pasha Kovalev, 39, in 2014.
The couple met after being partnered together on the BBC One show the previous year.
And after knowing each other for almost six years, Rachel revealed Pasha got her a very thoughtful gift to celebrate her 33rd birthday last month.
Rachel divulged to Express.co.uk at the Cirque du Soleil TOTEM premiere: ”He got me this coat for my birthday and he had this amazing denim jacket made.”
But the mathematician admitted the denim jacket was “completely mad” as it featured a mix of designs.
“He chose all of these details to go on it like all of this animals from our wildlife trip with my favourite colours and flowers and it’s completely mad, but it’s very cute.”
Rachel also admitted she was missing her beau, who is now halfway through the Strictly Come Dancing Live! tour partnered with Ashley Roberts.
The Countdown favourite said they are “used” to being away from each other due to their respective careers.
When asked if she misses Pasha, she spilled: “Yeah, but we are used to it, we have different schedules.
“But he’s working hard and we had a lovely birthday together.”
Meanwhile, Rachel was on spin-off 8 Out Of 10 Cats Does Countdown on Channel 4 last night when she opened up on her favourite moments from Countdown.
“You have done over 2,000 episodes of Countdown,” host Jimmy Carr said to Rachel. “What’s your high point and low point?”
Rachel replied: “Good highlight was when Ryan Giggs came on when I had done 1,000 episodes, pretty cool for me.”
The star continued: “Aside from that, I like it whenever we have our contestants back for the finals and the quarter-finals are done, every day Nick seems to forget that’s really funny when he says they’re coming back tomorrow for another semi.”
Laughing, she added: “Our floor manager has to walk across whisper in his ear what a semi is.”
Rachel looked stunning in the episode wearing a blush pink dress which put her lean pins on full display.
The blonde beauty showcased her slender physique in the stylish short frock, which featured a sheer design.
She teamed her look with a pair of white open-toe high-heels and wore her tresses in loose waves.
Countdown airs weekdays on Channel 4 at 2.10pm.
8 Out of 10 Cats Does Countdown continues Friday at 9pm on Channel 4.
