Jessica Simpson’s mother filed for divorce from her father a little under a month ago, and reports yesterday revealed a major bombshell as to why: Joe allegedly realized he’s gay and now has a young boyfriend. Radar Online spoke with a source in Jessica’s family today, who revealed she was “completely blindsided” by the news, especially because she thought she had such good “gaydar.” “She thinks she has very good gaydar, especially since a lot of her friends are gay,” the source said. “But she did not see this coming at all.” Despite the shock, she’ll still be sticking by her father’s side, no matter what his preferences are in love. See what the source had to say about that below.

“It was a complete shock to the system, she feels terribly for her mom who was left reeling by the announcement and her sister Ashlee has also taken the news quite badly.

“Jessica’s been trying to process the information slowly, but she’s having difficulty dealing with it. She can’t understand why Joe stayed married to Tina for so long, and can’t help wondering how much of their life was a lie,” the source continues.

“Despite that, she’s going to stand by him and support his decision. After all, he’s still her father and Joe’s always been there for Jessica whenever she’s needed him… And not just as a father, but as her manager too.”
