Kim's younger sister, Khloe, told Ryan Seacrest on Friday that the 35-year-old rapper might show up for the special event, which will take place Sunday in Beverly Hills.
"I think Scott and Lamar might bring Kanye," Khloe said on Secret's KIIS-FM radio show.
"That might happen at the end. That's what we were all deciding. Kanye said he feels like it's weird for him to be the only guy."
Kris Jenner, the Kardashian matriarch, told Seacrest that she was nervous about the prospect of Kim giving birth.
“I’m really just nervous about Kim giving birth and getting through this whole baby thing,” she said. “I’m excited and anxious at the same time.”
According to Hollywood Life, "garden chic" is the theme of the celebrity-studded shower. Kardashian's music box invitations were sent to the likes of Beyonce and Fergie.
