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. Marisa Mendez
