The blonde bombshell flaunted her curves in the skimpy sheer top as she paired it with skintight black trousers.
Louise’s figure took centre-stage as the sheer material flashed her white bra underneath as she spoke to two World Triathlon competitors.
She captioned the snap: “Massive congratulations to Jessica Learmonth and Georgia Taylor-Brown.
“Brilliant performances at World Triathlon Series Grand Final. Highlights on BBC 2 tomorrow and it’s a wrap!”
It didn’t take long for the compliments to pour in from her followers, as one posted: “You always look classy. Always!”
Another added: “Wow you look amazing Louise.”
A third chipped in: “Looking gorgeous Louise.”
A fourth wrote: “Love your top Lou.” Louise recently competed in a charity triathlon, and kept her fans updated with her journey.
She uploaded a picture of her standing in front of a ferry in skintight gym wear as she told fans what point she had got to in the competition.
She captioned the snap: “First sight of the fjord I will be swimming in for Norseman and I know I have to jump of a ferry in the dark, hoping it’s smaller than this cruise ship!
“This time I am not just competing because it’s a massive challenge but also to raise money for an excellent charity, thanks for all of your support, it’s much appreciated.”
It didn’t take long for her followers to send her messages of support for her hard work, as one posted: “Wow! I can’t believe you are doing this it looks really cool.”
