When asked by fans whom he ditched the purity ring for, the 27-year-old not only named the Twilight actress, but also revealed some intimate details from the night.

"I lost my virginity to this girl named Ashley. You can probably just Google it," he wrote. "It's quite the great story because I didn't have any condoms, so I went to our drummer Jack's room, who was my roommate at the time and I demolished his room looking for them."

Joe continued, "Found them underneath his underwear drawer. When he came home, he thought somebody broke into his room because his whole room was demolished because I was in dire need. Needed to happen then and now. Safety first, kids.”
