The college professor managed to stay under the radar, never receiving an eviction vote, on his road to winning his season, becoming Big Brother's first openly gay winner.
The 33-year-old picked the first time he won Head of Household has his favorite memory from filming.
"Every morning, production would play all of us pop songs to wake us up, and they'd usually cater to the tastes of whoever was HoH that week. My HoH reign was in August, so I jokingly kept saying that 'Christmas Shoes' was my favorite song in an effort to get production to play it one morning. On the last day of my HoH, they played it!"
He continued, "I woke up and immediately started laughing and ran downstairs and made everyone sit in the living room so we could listen together. Listening to a ridiculous, sappy Christmas song in the middle of August in the Big Brother house is a truly absurd moment that I will never forget."
Herren also revealed what he did with his prize money.
"When I was in college I lost roughly 100 pounds in a little over a year, so I had loose skin on my chest and stomach that I pretty much had no control over. So, I got elective skin removal surgery after Big Brother," Herren revealed. "It was roughly $20,000 out of pocket, but it was prize money well spent!"
Plus, he also took a month-long trip to Australia, diving on the Great Barrier Reef which "was a lifelong dream" for him.
Last month, Herren took to Twitter to sound off on the CBS reality hit's lack of "minority representation, " saying diversity "has always been atrocious" on BB.
