Kourtney Kardashian is making some changes to her staff after a large sum of money went missing.

In a new clip from Sunday’s episode of “Keeping Up With The Kardashians”, the 40-year-old reality star tells her sister Khloé, 35, one of her staffers allegedly stole $5,200 from her and her ex Scott Disick. An iPad was also missing.

“This lady stole $700 out of my wallet, then she stole $4,500 out of Scott’s,” Kourtney told Khloé. “Then my security, who’s here today, just said he’s seen her two times with her flashlight on in the office.”

After watching the alleged culprit get away with the goods, Kourtney takes action with the rest of her staff.

“We need to change the iTunes password, right now. We need to debug the house and I want to take every device and un-connect it from my phone. And next time, we’ve learned a huge lesson. They cannot step foot in here for an interview without us having their social, name, and address,” she says in the clip.

Later in a confessional, Kourtney said, “I obviously can’t change what happened, but like anything in life, I believe that this is a big learning lesson… I just want to start fresh and get this bad energy out.”
