The star shared a snap of her super-polished look before hitting up the ITV2 studios.
Jess' turned to her own bouffant-beautifying cousin - hairdresser Alix Wright - to create her style. Want to copy it? Here's how we're cheating the look.
Simply prep your locks with Batiste Heavenly Volume Dry Shampoo, £3.99 - it'll add fullness and grip, making it easier to style. Pull your hair into a side ponytail, leaving out some face-flattering strands.
Then wind the ponytail around itself to create a spiral-effect bun. Pin it into place using kirby grips and set with L'Oreal Paris Elnett Hairspray Precious Oils, £6.59 - a newly-launched spritz that delivers both hold and shine.
It wasn't just Jess' tresses that caught our eye. A pastel pout, contouring and shimmering pink-toned eye shadow - created by her go-to make-up artist Krystal Dawn - completed her pretty get-up.
The star also posted a picture posing with host Keith Lemon - we can't wait to see her on the show tonight!
