It looks like the supposed unbeatable pair in "Keeping Up With The Kardashian" have been knocked down. Rumors about Kourtney Kardashian and Scott Disick's split continue and custody over their three kids is now brought up.

According to Hollywood Life, Kourtney has had enough and is ready to pull the plug with regard her relationship with Disick. She has reached her breaking point is geared up to fight the custody battle for their three children.

In addition to the reports, the oldest Kardashian sister kicked out Disick from their home and is talking to her lawyers to get full custody of Mason, Penelope and Reign.

"Her team of lawyers has been notified that she's gearing up to fight for full custody of their children, too," an insider said.

In another report by Latin Post, Kourtney has decided it's time to cut Disick off when rumors broke out that he spent four days in a New York City hotel with a 21-year-old woman.

"She called Scott after the story about his latest infidelity came out and told him he'll never see his kids again. You can't blame her that would break any relationship up," a source said.

The two reportedly had their biggest fight so far and Kourtney walked out feeling the need to protect her children from their father who refused to slow down his partying habits.

"Kourtney feels she has no choice but to fight for full custody of the kids, unless he can behave like a real dad. Realistically, Scott doesn't stand a chance in a custody battle," the source continues.

The 36-year-old mother of three was recently spotted in a Los Angeles restaurant while in deep conversation with a female friend. The Kardashian didn't look so happy as she mentioned Scott's name a few times.

Over the years, Kourtney and Disick have managed to patch their differences and fights. However, it looks like a big blow for Kourtney this time. The 32-year-old who likes to refer to himself as Lord Disick has been long rumored to have cheated on Kourtney with her sisters. There was an incident when he reportedly was so drawn to Kendall that he proposed to her and promised to leave Kourtney.

In addition, the two have been having trouble for some time as Kourtney is said to have zero trust in Scott. A source adds that Disick is not allowed to be alone with the kids for some time now. Nannies and helpers were always close behind whenever Scott is around the children and Kourtney is not present.
