Socialite-turned-reality TV star KHLOE KARDASHIAN is to marry her basketball player beau LAMAR ODOM in a shock wedding this weekend, according to U.S. reports.

The pair started dating last month and now the Los Angeles Lakers hunk, a father of two, is planning to make Kim Kardashian's little sister his bride.

Odom and Kardashian will exchange vows at a private residence in Los Angeles on Sunday, according to Life & Style magazine.

A close friend of the couple tells the publication, "The wedding planner, photographer, groomsmen and bridesmaids have all been chosen. It's chaos at the Kardashian household!"
