It’s not an optical illusion, it’s Khloé Kardashian.

The buxom reality television star has been on a serious slim-down since splitting from Lamar Odom, but unveiled an even more dramatic silhouette on Instagram on Friday.

Kardashian, 29, snapped a sideways shot of her signature curves in a pair of jeans, accentuated by the help of a waist trainer, or a corset.

“I love my waist trainer from @premadonna87!!!! Miss@blacchyna has me obsessed!!!” she captioned the photo. “Who doesn’t love to feel tight and right?!? #whatsawaist #waistgang#Fitness #GetItRight”

Though Us Weekly reports that Kardashian lost 30 lbs. in 2013, she may be using the age-old practice of waist-training or corsetting to lose an extra inch or two from her waist, while helping emphasize her hourglass figure.

One person who seems to be enjoying Kardashian’s new shape is her rumored boyfriend, French Montana.

The couple were recently spotted getting cozy at Greenhouse, during a party for VH1′s “This Is Hot 97.”
