The guest list for Kim Kardashian and Kanye West's upcoming wedding has begun to leak, according to Us Weekly.

The magazine says several celebrity friends of reality-TV star Kardashian, 33, and rapper West, 36, are attending the wedding weekend, which includes a rehearsal dinner in Paris and a formal ceremony in Florence, Italy, reportedly at the Forte di Belvedere. Workers there told Us they are busily preparing the venue for the wedding, although it was unclear if they meant the ceremony itself or, as "Entertainment Tonight" has reported, just the reception.

Rapper and music mogul Jay Z will be among the guests, Us said, though his wife, pop star Beyoncé, remained undecided. Singer John Legend and his wife, model Chrissy Teigen, are attending, along with rapper Q-Tip, whom the magazine said might DJ, and rapper Tyga and his girlfriend, Blac Chyna.

Sports figures include tennis champion Serena Williams; the New York Knicks' Carmelo Anthony with his wife, reality-TV star La La Anthony; and former NBA star Scottie Pippen and his wife, ex-model and former "The Real Housewives of Miami" cast member Larsa Pippen.

Others include "Girls Gone Wild" founder Joe Francis and his girlfriend, Abbey Wilson, stylists Chris McMillan and Jen Atkin, jeweler Lorraine Schwartz and Vogue contributing editor Andre Leon Talley.

And, naturally, Kardashian family members will be there: Kardashian's mother and stepfather, Kris and Bruce Jenner; sisters Khloe and Kourtney, with the latter's boyfriend and two children; brother Rob; half-sisters Kendall and Kylie Jenner; and stepbrother Brandon Jenner. Us previously noted that stepbrother Brody Jenner chose not to attend when his girlfriend was not invited.
