Love is elusive for the Humphries family these days — TMZ has learned that Kris Humphries’ parents are going through a divorce of their own. 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?It’s unclear how long the couple was married … but it was definitely longer than 72 days.
