EXCLUSIVE: How Kim Kardashian and Kanye West Are 'Reassessing Their Security' After Paris Robbery

Kim Kardashian West's terrifying robbery in Paris definitely has her and husband Kanye West rethinking their security measures, a source close to Kim tells ET.

After the 35-year-old reality superstar was held up at gunpoint on Sunday when armed, masked men entered the luxury apartment she was staying at in Paris, France, during Paris Fashion Week, security around the couple and their two children -- 3-year-old North and 9-month-old Saint -- is set to change.

"Kim and Kanye are reassessing their security detail now. Kanye is freaking out -- this really threw him for a loop," the source says. "There will be a lot of things that change now in terms of security, especially with the children."

"Their immediate need is undercover security -- people who will be with them but stepped back to the side," the source adds. "There are plans for many other things they'll change as well."

Most importantly, the famous family is trying to figure out how to prevent an incident like this from ever happening again.

"Kim is constantly traveling and sleeping in hotels," the source explains. "For her to get through this experience will take some time, mentally."

Though Kim is "absolutely traumatized," the source says she holds no grudges towards her bodyguard, Pascal Duvier, or with French authorities. A source previously told ET that Pascal was not with Kim during the robbery on Sunday -- he and the driver dropped Kim off at her apartment through the garage, and Pascal went back out with her older sister, Kourtney Kardashian, who met up with their younger sister, Kendall Jenner.

"He was done working for her when this happened," the source says about Pascal. "Also, Pascal is not an armed bodyguard. Kim does not hold Pascal responsible for one second."

Kim, Kanye, and their kids are currently staying at their New York City apartment. Kim's mother, Kris Jenner, is also set to stay with them until Wednesday, the source says.

"She's just spending time with her kids right now and hugging them really tight," the source adds.

Both North and Saint were safely in NYC with Kanye, a family friend, and a nanny during Kim's scary incident over the weekend, a source told ET on Monday. More specifically, North was at a performance of the musical Matilda on Sunday afternoon, a rep for the Broadway production confirmed to ET.
