Cara's boyfriend Nathan Massey was responsible for the snap, after taking a sneaky pic of his girlfriend in her new Calvin Klein underwear.
Sharing it with his Instagram followers, Nathan gushed: "When you get your girl some CK undies. All girls should wear these @cara_delahoyde."
That derriere is insane!
Of course, it didn't take long for Nathan's post to go viral and Cara has been inundated with compliments about her rump - including one from none other than Geordie Shore's Holly Hagan.
Holly tweeted Cara her appreciation and simply said: "@Miss_Delahoyde UNREAL."
Cara thanked Holly for her tweet and replied to another Twitter user, blaming her new American diet on her bootylicious frame. She and Nathan are currently holidaying in Florida, after he promised Cara a trip to Disney.
Cara joked: "It's this unhealthy American diet going straight to that [peach]."

Cara causing a stir with her CK clad bod comes after she and Nathan have been making the most of their trip across the pond.
The Love Island couple have been sharing plenty of photos from their Disney trip, with Nathan telling fans: "This holiday was just what we needed !!!! Had the time of my life I ain't gonna lie (sic)."
Cara, meanwhile, said she'd had the most "magical" day with Nathan at Disney's Magic Kingdom.
She and Nathan first met while starring on Love Island's second series on ITV2 this summer. They were coupled up from the get go and viewers watched romance blossom between the pair.
Now, they are an official couple and five months after filming wrapped, Nathan and Cara are living together in Essex and have welcomed a new addition.
Before you get too ahead of yourselves, that's their pet pup Sonny. Not a baby - that's Cally Jane Beech and Luis Morrsion. The original Love Island stars are expecting their first baby together.
Cara and Nathan, however, are practicing their parenting skills with a puppy.
Sharing a photo of little Sonny online last month, Nathan gushed: "Now tell me this ain't the cutest little sod u have ever seen," before joking: "Congrats to @cara_delahoyde to giving birth to such a beautiful child."
