Dr. Will Kirby, known as the "Big Brother 2" champ, is a single man once again ... because his divorce from Erin Brodie has been officially finalized.
The judgment, obtained by TMZ, shows neither party will pay any spousal or child support -- he and Erin will share joint legal and physical custody of their 2 kids.
According to the docs, Will gets to keep his dermatology practice ... as well as his jewelry, artwork, and -- most importantly -- the dog, Wriggley. Erin walks away with all her personal items.
They'll continue to co-own their L.A.-area property ... and the docs indicate they plan to hold onto the spot until their young daughter graduates from high school, at which point they'll look to lease or sell the pad.
As we reported, the dermatologist filed for divorce last year after nearly 4 years of marriage.
Will and Erin at the time told TMZ in a joint statement, "Our relationship is stronger than ever, just not in a traditional sense. We remain committed to being the best parents to our two children and supportive of each other as we navigate through this transition."
