Although Kim Kardashian wasn't seen arriving at Kendall Jenner's birthday party on Wednesday, the mother-of-two is said to have attended a dinner for the 21-year-old earlier in the night by sneaking in through a private entrance.
Sources tell TMZ that the 36-year-old was surrounded by three bodyguards at all times during the intimate gathering at Catch restaurant in LA.
An insider claims the brunette beauty paid each security officer $100 per hour and didn't wear any jewelry to the pre-party, which only included about 20 guests.
It was also revealed this week that Kim and hubby Kanye West parted ways with their longtime bodyguard Pascal Duvier.
The 43-year-old was at a nightclub with Kendall and Kourtney Kardashian when Kim was held up at gunpoint in Paris last month.
"Kim and Kanye are reassessing their security detail now. Kanye is freaking out — this really threw him for a loop," a source previously told Entertainment Tonight. "There will be a lot of things that change now in terms of security, especially with the children."
