Joe Simpson, 54, and Tina Simpson, 52, Ashlee and Jessica Simpson's parents, have filed for divorce after 34 years of marriage.
The couple filed a divorce petition in McLennan County, Texas on September 24. News of the split emerged the same day the National Enquirer claimed that Joe Simpson is gay.
"It is an amicable split and there is no third party involved," a rep told E! Online on October 22, slamming the rumors. "Any other related allegations are completely false. The family appreciates your respect for their privacy at this time."
Joe Simpson was recently charged with two counts of DUI, after being pulled over on August 15. If convicted of both charges, Simpson could face up to 6 months in jail and up to $1000 in fines.
The former minister, who goes by the Twitter handle of Papa Joe and manages his daughter's careers, rose to notoriety after saying of his daughter Jessica, "She just is sexy. If you put her in a T-shirt or you put her in a bustier, she's sexy in both. She's got double D's! You can't cover those suckers up!"
Joe and Tina's divorce will be the third for the Simpson family. Jessica filed for a divorce from Nick Lachey in 2005 while Ashlee Simpson filed for divorce from Pete Wentz in 2011.
Jessica Simpson and her fiance Eric Johnson welcomed her first child, daughter Maxwell Drew, on May 1. Shortly after, Simpson signed a multi-million dollar deal with Weight Watchers to be the weight loss program's newest spokes model.
Ashlee Simpson is mother to Bronx Mowgli Wentz, her 3-year-old son with her ex-husband, Fall Out Boy member Pete Wentz. She is currently dating "Boardwalk Empire" star Vincent Piazza.
