According to The Famous People, Kristen Austin is Stone Cold Steve Austin's current wife. The couple married in 2009 and have remained married for over 11 years.
Unlike his previous three marriages, the present Mrs. Austin was neither a childhood love nor a wrestler. After his first divorce, Austin married fellow wrestler Lady Blossom (Jeanie Clarke) (says IMDb). In their seven-year marriage the couple had three daughters — Stephanie, Loren, and Cassidy. Austin also has another daughter, Jade Adams, whom he adopted; Jade is the biological daughter of his second wife. For his third marriage in 2000, Austin married Debra Marshall, a popular wrestling valet at the time. However, it was another failed marital relationship for Austin, and by 2003 he was separated again. After the split, Marshall alleged that Austin was a domestic abuser who used steroids (per WWF Old School).
They say the third time's the charm, but maybe in Austin's case it was the fourth. Since his most recent marriage he's kept a mostly low profile. Not much is known about his wife Kristin — PS Power Sportz pointed out a year ago that "she has not revealed anything about herself" prior to her marriage to Steve — but we do know the pair have no children together, and his marriage to her is his longest (so far).
