Carol Vorderman was thrilled by the rugby as she danced around in a pair of bright red leather trousers.
The triumphant TV presenter, 58, celebrated Wales' win with delighted jumps for joy in photos uploaded to her Twitter account.
Carol, whose mother was Welsh, got into the spirit of things in a big way, writing tweets including: Dwi'n CARU CYMRU AM BYTH @WelshRugbyUnion @rugbyworldcup CRYING CRYING CRYING WE LOVE YOU BOYS".
She also wrote: "We are BELIEVERS..... @WelshRugbyUnion @rugbyworldcup ".
In the photos, Carol shows off her incredible figure in the skin tight trousers paired with a rugby shirt.
While the nation celebrated the win against France, some of Carol's fan were more distracted by her atire.
Carol, who used to host Countdown, won Rear of the Year in 2011 and in 2014.
"OMG Ms Vorderman how did you get those pants in, so tight... so sexy!" declared one.
"What an amazing a**e x your a stunning woman xxx" gushed another.
A third wrote: "Wow that’s all I’m celebrating is them tight leathers" alongside a blushing face emoji.
Wales beat France 20-19 yesterday to reach the Rugby World Cup semi-finals.
This is not the first time Carol's eye-popping skin tight outfits have had her fan's pulses racing.
She posted photos on Twitter in August to show off her newly dyed blonde locks.
She looked stunning in tight outfit, pouring her curves into a pair of leather trousers.
She also donned a fitted white jumper that looked like it was struggling to contain her ample cleavage.
Carol teamed the look with a pair of high heel boots as she posed for the mini photoshoot in a stairway with her hairdresser.
