Kourtney Kardashian’s younger sisters, Khloe and Kim, are planning a “sleek, chic and elegant” baby shower for the mom-to-be next month.

Kourtney, 30, who is due to give birth to her first child with boyfriend Scott Disick in December will be guest of honor at the event in Los Angeles Nov. 14. Invites shaped as baby-blue angel wings went out to approximately 75 friends and family this week: “Please join us for a baby shower honouring Kourtney Kardashian, November 14, 2009, Noon.”

Party planner Sharon Sacks was hired by Kim and Khloe to make sure the shower is a memorable affair. “The magic words I just kept hearing were sleek, chic and elegant,” Sacks told X17Online.com this week.
