The sexy model was filming herself alongside pal and fellow fitness model Julianne Klaren when the wardrobe mishap occurred.
Wearing nothing but a tiny khaki vest top tied up at the waist and a pair of hotpants, the blonde beauty danced and smiled for the camera.
But at one point in the live stream to her 2.8million adoring fans, the social media star sat down next to brunette Julianne.
As she smiled and shimmied for the camera, the strap of her top fell down, leaving her momentarily flashing her nipple.
She quickly pulled her top back up in a desperate bid to cover her exposed boob.
The busty babe then laughed and quickly ran out of shot, red-faced.
