The ballroom champion, 33, looked incredible in the skin-tight piece, which featured a cheeky low waist and subtle ruching detail. Dianne certainly upped the ante when it came to colour with the look as she also added a bold pink sports top to complete the gym-ready ensemble.
The dynamic outfit was worn by the star to the book launch for her brand new wellness book Move Yourself Happy, which was released last week.
Accessorising the fabulous look, Dianne added a pair of dramatic drop earrings featuring gold hoops and adorned with multi-coloured tassels. She also rocked a pair of fresh white trainers and matching socks.
As for her hair, Dianne left her long flame-hued tresses down and straight, and it couldn't go unnoticed how much they matched her vibrant leggings.
The professional dancer also opted for a face of natural makeup comprised of subtle nude lipstick and lashings of mascara.
The stunning photo, which saw her posing in her lavish Sussex abode, was part of a 'photo dump' showcasing what appeared to be an incredibly fun week for the star.
Other photos showed her heading out on a date night with her adoring boyfriend, Joe Sugg, as well as attending his sister, Zoe Sugg's, 33rd birthday celebrations.
Friends and fans of the star couldn't get enough of the incredible update. One penned: "The third picture I canttt!! Congrats on today Dianne! You're absolutely smashing it."
