Meghan King Edmonds is about to celebrate another major family milestone. The Real Housewives of Orange County mom's stepdaughter Lauren Edmonds, the daughter of husband Jim Edmonds, is getting married. 

Meghan recently celebrated Lauren's upcoming nuptials at her Kentucky Derby-themed bridal shower. "[C]an't believe she's getting married!" Meghan captioned a lovely photo of herself with Lauren and stepdaughter Hayley Edmonds.

Lauren's loved ones also posed for this epically elegant photo.

In addition to Lauren and Hayley, Jim has two other children from a previous relationship: Landon and Sutton. Jim welcomed his first child with Meghan, daughter Aspen King Edmonds, in November 2016.
