Jared Fogle -- FBI Reportedly Have Texts Bragging About Sex With 16-Year-Old

Jared Fogle reportedly paid $100 to have sex with a 16-year-old girl ... an encounter he called "amazing."

The FBI has subpoenaed text messages between Jared and a Subway employee with whom he was having a sexual relationship, according to Business Insider, which broke the story.

According to the report, in 2008 Jared wanted the woman to advertise herself on Craigslist to have sex with other men so he could watch. He allegedly said he'd pay $500 per encounter. Business Insider says the woman responded, "Is this the same website you found that 16-year-old girl that you f*****? I still can't believe you only paid $100 to her."

The report says Jared responded, "It was amazing!!!"

The woman says she went to Subway to complain, but the company did nothing.
