The 34-year-old brought his friends to New Orleans from his hometown of Laurel, Miss., and Los Angeles, he announced on his SiriusXM show "Dirty Pop With Lance Bass" on Sunday (Warning: audio contains profanity.) "I thought it was the perfect combination of [people and location] to do what I've been wanting to do for a while, which is propose," Bass said. However, he added that he had a hard time losing his fiance so he could to track down an engagement ring. Trying to find a ring in New Orleans was "impossible," he said. They don't make guy rings; someone needs to start some sort of line for gay men's rings. Bass finally found the David Yurman ring at Saks Fifth Avenue and en route to a karaoke bar, he pulled Turchin toward a park near a church and popped the question. "I always knew that's where I wanted to propose," he said. I got down on one knee and I proposed, right in front of Jackson Square, my favorite place. ... I was pretty nervous.

The "Dancing With the Stars" alum announced he was gay on the July 26, 2006, cover of People. "The thing is, I'm not ashamed -- that's the one thing I want to say," he said in the mag. I don't think it's wrong, I'm not devastated going through this. I'm more liberated and happy than I've been my whole life. I'm just happy. Meanwhile, Turchin called himself the "happiest guy in the world" and was busy fielding congratulatory thank-yous on Twitter, including tweets from Bravo's Andy Cohen and "Once Upon a Time" actress JoAnna Garcia.
