Kourtney Kardashian's mom, Kris Jenner, will host a baby shower for her daughter in November at the family's L.A. home, Kourtney reveals to PEOPLE exclusively.
"The guest list is around 75 right now, and I don't want it to be much more than that," Kourtney, who's expecting
her first child with boyfriend Scott Disick around Christmas, says. "A lot of my friends from college have babies, so I'm inviting a lot of them. And some of my family members, like my aunt, were talking about doing a family baby shower."
Keeping the guest list under control for the is proving to be a difficult task, considering the Nov. 14 soiree's organizer: her mom. "All my mom asked me for is a list," says Kardashian. "I sent her the names of people, and she emails me back, 'Yes, those people, but invite so-and-so!' So she's always adding!"
The shower's theme remains up in the air, but Kardashian expects the gathering to be a show stopper. "I don't know what they have planned exactly, but [my sisters] Kim and Khloe, and my mom are all planning my shower," the Kourtney & Khloe Take Miami
star, 30, tells PEOPLE. "I'm sure my mom has been planning this since I was little. She is big on showers, so I'm sure mine will be a big event. I'm very mellow. I'm not as over-the-top as my mom, and Kim and Khloe."
Although Khloe is a newbie to baby shower planning, Kourtney says, "Khloe just had a big shower at my mom's house for [actress] Lauren London, so I think that was a warm-up for her. She's never done a shower. A lot of my friends also keep offering to get involved."
Kourtney says planning such an event isn't her strong point. "I'm totally not a theme person, and I'm sure my mom already has it figured out."
In fact, Kardashian says she relates to Cynthia Nixon's character, Miranda Hobbes, in an episode of Sex and the City
, during which she accepts her friends' offer to plan a baby shower, as long as clichés, such as plastic storks, are banished from the event. "She was like, 'I don't want any storks!' That's like me. I want it more chic. I want it to be a stylish baby shower."
And will her beau Scott be at the shower? "I don't know if you're allowed to have guys! I have to ask my mom!"
