Kourtney Kardashian reveals her pain in cyptic tweet after ex Scott Disick is pictured partying in Mexico

Their turbulent romance has had its share of ups and downs but after Scott Disick was snapped partying with a bevy of bikini-clad ladies in Mexico, Kourtney Kardashian made it clear that she was not impressed.

Disik – who checked out of rehab in November after a month of in-patient treatment – was in his element during his sunshine break at Girls Gone Wild founder Joe Francis' lavish home in Mexico. He enjoyed the company of beautiful scantily clad woman as he lounged in front of the pool.

In a cryptic post about 'heartache' the 36-year-old Keeping Up With the Kardashians star Kourtney appeared to have responded to her ex's antics. The mother-of-three let her feelings be known in a message that read: "A smile hides my pain, a hug masks my heartache, and a laugh covers my tears."

Kardashian and Disick split in July 2015 after their relationship was rocked by fresh cheating allegations. It all came crashing down after the renowned party boy was pictured getting close with his alleged former girlfriend Chloe Bartoli on holiday in St Tropez. In pictures published on the Mail Online, they were shown cuddling and at one point, Bartoli feeding the reality star food.

"Kourtney has always taken Scott back and been by his side, but now with three kids it has gotten old," a source told E! News at the time. "Kourtney has to do what's best for the kids."

"Scott has been running around saying he's single," the insider added. "Kourtney dumped him after she saw the pics [in Monte Carlo] and he hasn't been home after a month-long party binge."

In February, Kardashian hinted that the pair were taking steps to get back together after Disick attended a number of family occasions. He was present at the dinner organised by Kris Jenner to celebrate what would have been the 72nd birthday of the late Robert Kardashian – the father of Kourtney, Kim, Khloe and Rob Kardashian. Following the dinner, Kourtney tweeted that it had been a "blessed and magical night", along with a heart emoji, prayer hands, and a red rose.
