"Tina and Joe Simpson have filed for divorce," the statement reads. "It is an amicable split and there is no third party involved. Any other related allegations are completely false. The family appreciates your respect for their privacy at this time."
High-profile celebs in their own right, the pair were featured on both of their daughters' MTV reality shows: Jessica's Newlyweds (with first husband Nick Lachey) and Ashlee's Ashlee Simpson Show; known affectionately as "Papa Joe," their father, a former pastor, is the longtime manager to singer/actress/designer Jessica, 31, and singer/actress Ashlee, 28.
The twosome recently became second-time grandparents when Jessica and fiance Eric Johnson gave birth to a daughter, Maxwell Drew, in May; Ashlee and ex-husband Pete Wentz share son Bronx, 3.
