The petite singer, 25, showed off her killer abs in a tiny white crop top and teamed it with a leather jacket and fitted printed trousers, which certainly made her stand out next to model Jourdan.
In fact, Jade might just have stolen the limelight from her pal, who decided to dress a little more casually for their dinner date.
Jourdan, 22, kept her outfit simple with a pair of ripped jeans and an oversized sports top. However, she still managed to add that glam factor by adding a slick of bright red lipstick to her look and a pair of white heels.
The pretty pair spent their evening at the Crazy Bear restaurant and bar in London and seemed to have had a great time together, as Jade later tweeted: "Awww fun night! @missjourdandunn"
However, things took a turn for the worst for Jourdan, who admitted that she'd lost her phone during the night and couldn't help expressing her frustration over Twitter once she'd returned home.
The catwalk queen - who has also modelled for Rihanna's River Island clothing collection - tweeted: "Lost my iPhone.........extremely pissed.
"Yes tears were shed"
Jade and her Sugababes band mates have taken some time out from recording lately it seems, as the original Sugababes girls - Mutya Buena, Keisha Buchanan and Siobhan Donaghy - have reformed and named their group MKS (or Mutya, Keisha, Siobhan).
However, Jade - who also appeared on Tom Daley's diving show, Splash, this year - has insisted that there is no rivalry between the two bands.
