Exes Kourtney Kardashian and Scott Disick seem to be lashing out each other by posting pictures of themselves enjoying lavish vacations on Instagram.

The 36-year-old mom of three went to St. Barts with the Kardashian and Jenner broods while Disick hopped on to his private plane to Puerto Vallarto in Mexico with his close pals including Joe Francis, a family friend to the Kardashians, US Weekly scooped.

As expected, these former sweethearts posed and snapped in their respective destinations to share it with fans. However, people cannot help but wonder if there are subtle motives as to what seems to be an Instagram war between the two. Mail Online posted a barrage of Kourtney's paparazzi photos while on the said vacation including shots of younger sister Kendall Jenner playfully posing before the cameras and toting young niece North from another sister, Kim.

Despite this anticipated publicity of their own little getaway, Kourtney made sure her ex knows what he left behind by posting a picture of her stunning figure as she posed under palm trees in a metallic swimsuit, Inquistr said.

Meanwhile the self-proclaimed 'Lord' Disick has also posted a picture of himself enjoying his time with pals Francis and Darren Dziensciol with the caption "little boy time in mex," followed by another photo of himself wearing casual shorts and t-shirt while lying on one of his private plane's wings before leaving for home.

According to US Weekly, their sources said that Disick is still hoping for a reconciliation with Kourtney and texts her "I still love you" and "I want you so bad" day and night. However the eldest Kardashian is firm in her decision of not taking him back if he would not clean up his act.

The former pair has three kids: Mason, 5, Penelope, 3, and eight-month-old Aston, in their ten year relationship which ended last July.
