Kris Humphries Parents Also Divorcing

According to documents filed in Minnesota, Kris' mom Debra filed for divorce from husband William earlier this month. The couple has three adult children -- Kris and his two older sisters, Krystal and Kaela.

There will be some serious burger money up for grabs in the split -- William owns several Five Guys Burgers and Fries restaurants throughout Minnesota.

It's pretty ironice ... Kris is fighting a divorce from Kim because he says it goes against his religious beliefs. Perhaps it's time to take a cue from mom?
