TINA SIMPSON pens suicide note after discovering hubby JOE – Jessica’s dad – was having a gay affair.

Shortly before traveling to New York to confront Joe, 52, about his tryst with 21-year-old model Bryce Chandler Hill in August 2012, Tina scrawled a cry-for-help letter threatening to shoot herself after she discovered her husband’s homosexual tendencies, a source tells RadarOnline.

In the note, Tina, 53, also said she wanted to shoot Joe , her husband of 35 years, for cheating on her, a family insider reveals.

Tina left the note in the Encino home she shared with Joe and he found it!

Joe immediately handed it to his lawyers who were handling his divorce

“Tina was so distraught when she found out about Joe’s secret gay affair, she immediately wrote a suicide note,” a source said.

 “It was fairly detailed and she said she wanted to shoot herself for what Joe had done to their 35 year marriage. Worse still, Tina wanted to shoot Joe as well. She was just so angry with him.

“But, instead of killing herself, Tina headed straight to a New York hotel to confront Joe about Bryce Chandler Hill.

 “However, when Joe returned to the Encino home in Los Angeles they shared, he found the note, made a copy and gave it to his divorce lawyer as a bargaining tool for the settlement.

Tina eventually offered Joe half of the family fortune.
