People close to the McKibbin family tells TMZ that Nikki's death was caused by a brain aneurysm. Following the initial incident, McKibbin was on life support until being taken off assistance at 3 a.m. on Sunday. She was then pronounced dead by officials and her organs were harvested.

Her 15-year-old son, Tristan Langley, also auditioned for the show in 2014 and made it to Hollywood, but didn't go the distance. Along with American Idol, McKibbin appeared on Fear Factor, Battle of the Network Reality Stars, as well as documented her battles with substance abuse on Celebrity Rehab and Sober House.
