Jessica Simpson is reportedly "shocked" to hear claims that her father Joe Simpson - a former Baptist minister - is gay and dating a male model.
A source told RadarOnline that the 32-year-old singer - who recently gave birth to daughter Maxwell and is planning her wedding to fiance *Eric Johnson *- is struggling to come to terms with the news.
"Jessica had absolutely no clue that her father was gay, not even the slightest inkling," the source told RadarOnline. "She thinks she has very good gaydar, especially since a lot of her friends are gay, but she did not see this coming at all."
The shock rumour comes in the wake of news that Jessica's mother *Tina Simpson * filed for divorce from Joe last month. The couple had been together for 35 years.
It was reported last week that Joe, 54, pictured left with Jessica, had allegedly been having an affair with 21-year-old male model Bryce Chandler Hill, although Hill has taken his Twitter page to adamantly deny the claims. "Yes, I've read the story - it's simply NOT TRUE," he wrote.
According to a friend of the Simpson family, Hill met Joe through a mutual friend who is close to Jessica and her sister Ashlee Simpson.
The source also revealed that Hill was "taking Joe for a ride" and using him to get famous.
"Bryce is desperate to become famous, he's done lots of modelling shoots and wants to become an actor," Hill's friend told Radar Online.
