Kourtney Kardashian is certainly showing Scott Disick what he's missing in this pic.
Taking a tip from her selfie-loving sisters, Kourtney snapped a pic of herself wearing nothing but a little black bikini.
The mother-of-three credited her youngest sister for sharing the sexy shot to her 21.8 million Instagram followers on Thursday, writing: "@kyliejenner taking over my Instagram feed."
Kourtney has not shied away from social media at all since her split from Disick. In fact, she seems to be using the platform to embrace her vulnerability.
On Wednesday, the 36-year-old reality star tweeted a powerful video of a 2011 TED Talk called "The Power of Vulnerability," delivered by author Brene Brown. The 20-minute video deals with human nature, our ability to empathize, and the way we can found our true self-worth in the midst of heartbreak and emotional turmoil.
As for how Kourtney's doing since the split, Kris Jenner recently spoke to ET about her oldest daughter.
"She's good. Kourtney's good," Kris said, resolutely. "[She's] hanging in there."
In July, it was revealed that Kourtney and Scott, 32, had broken up shortly after he had been spotted with another woman in Monte Carlo.
The former couple have three children together -- 5-year-old Mason, 3-year-old Penelope and 7-month-old Reign.
