Kourtney Kardashian is rumored to be as angry at Scott Disick as she's ever been after he left her at home with their three young children this Independence Day weekend, only to be later snapped in France engaging in acts of PDA with a reported past girlfriend.

Hollywood Life has since identified the woman getting close and cozy with the 32-year-old Disck as Chloe Bartoli, an alleged ex-gal pal.

"Kourtney is once again embarrassed by Scott's behavior and she has been made aware of these pictures," a source said. "She is absolutely livid with what she has seen. Her mind is racing on what else could be happening."

It's hardly the first time Disick has been suspected or accused of being unfaithful. Hollywood Life has previously reported he recently spent four days allegedly holed up in a New York City hotel with an unknown woman.

It all prompted a source to recently claim Disick has slept with at least 100 women over the nine years he and Kardashian have been a couple.

Drugs and alcohol are also rumored to play a big part in Disick's dysfunction. In the case of the NYC incident, a friend of the woman involved claims Disick was "doing a lot of cocaine" during their hookup and avoiding Kourtney's calls.

Over the years, Disick is also rumored to have slept with sisters Khloe, Kendall and Kylie. Reportedly, he once became so infatuated with Kendall Jenner that he proposed to her and vowed he would leave Kourtney so the two could start a life together.

Rumored to already have kicked him out of their family home, Kourtney is now reported to be threatening Disick with the prospect of seeking full custody of their three young children, Mason, 5, Penelope, 2, and Reign, six months.
