New reports suggest Kourtney Kardashian and longtime boyfriend Scott Disick are over. The pair have been together since 2006 and now have three children together. 

TMZ reports Kourtney made the difficult decision to kick her baby daddy to the curb after her refused to give up his party boy lifestyle. Sources said the 32-year-old has not returned to the Calabasas mansion he, Kourtney and their three young children share in more than a month. The decision to dump Scott was not an easy one for Kourtney, however she felt she had to do what was right for her children. 

Scott isn't the only one she's reportedly fed up with. Sources say the 36-year-old "Keeping Up With the Kardashians" star feels her ex has a drinking problem and his friends are adding fuel to the fire. According to TMZ she feels they're enabling his drinking and partying.

Scott seems to be handling the break up in stride. He was spotted sitting poolside with celebrity stylist and ex-girlfriend Chloe Bartoli in Monte Carlo July 2. The reality star was photographed getting handsy with the 25-year-old by the pool and in a local restaurant throughout the holiday weekend. 

This isn't the first time the couple has split. As you may recall, Kourtney made the difficult decision to break things off with Scott shortly after the birth of their eldest son, Mason Disick. At the time Kourtney and her famous sisters were filming "Kourtney and Kim Take Miami" Season 2. Scott spent much of the season at the club, leading to a nasty confrontation between he and Kourtney. Scott grew angry and drunkenly punched a mirror. Kourtney packed up her infant son and left the hotel room in which they were living for the summer. 

Neither Kourtney nor Scott have addressed their rumored split.
