"I tried [dating]. I actually dated 30 guys at one time. I don't know if you know this," Hannah quipped, referring to her The Bachelorette stint earlier this year.
"I spent a whole year of my life trying to date, and it still didn't work out."
After getting dumped by Colton Underwood on The Bachelor's 23rd season, Hannah starred on The Bachelorette's fifteenth season and got engaged to Nashville-based country singer Jed Wyatt, only to dump him five weeks later because Jed had lied to her about his dating history.
Jed initially told Hannah that his romance with ex Haley Stevens ended one week before taping commenced, but Haley told People in June that Jed left Nashville to film the show in March still dating her.
In addition, Haley alleged in her interview that Jed had told her he was only going on the show to promote his music and they'd resume their relationship once he returned home.
Tyler Cameron, a general contractor and aspiring model from Florida, finished as Hannah's runner-up on The Bachelorette.
Hannah and Tyler reunited after The Bachelorette finale aired and spent the night together on August 1 in Los Angeles, but then he seemingly moved on days later to pursue a romance with supermodel Gigi Hadid.
Tyler, however, just ended his summer fling with Gigi earlier this month, and now both he and Hannah are single.

"I have been so busy and I think he's been so busy," Hannah told Justin when asked how things have been going with Tyler. "I wish him well and I'm just focusing on me right now because that's really important."
"No! I'm not. I'm not [dating him]," Hannah assured Justin.
"We're great friends. He kind of has to be my best friend, so I make him be. He cries about it. But no, it has been an amazing experience... I have just [experienced] trauma from dating, so we're not going to do that right now -- we're going to dance!"
Hannah has been through a lot in the last year, but she also gushed about everything she has to be thankful for.
"It's been an amazing year. I cannot believe this is my life, but man oh man! There's been a lot of things!" Hannah said, adding that Dancing with the Stars has been a wild ride.
"I have had so much physical pain from all of it, but it's emotional too. I have a lot of baggage as well, so going from one show to the next, it's been a lot. It's been a lot, but I really can't complain because I am living this dream life too -- with a lot of blisters!"
Dancing with the Stars' eight remaining couples will surprise and spook fans with "Halloween Night" performances on Monday, October 28, including team dances.
One more couple is expected to be eliminated from the Season 28 competition at the end of the broadcast.
