Alan previously said he's swearing off all future DWTS showmances after his whirlwind romance with social-media model and influencer Alexis Renfell through in 2018 after they had competed onDancing with the Stars' 27th season together, and he apparently still feels the same way.
However, Alan claimed the speculation didn't bother them and they just "shut it all out."
"We knew people would talk and assume, especially since she was the Bachelorette and I'm still single," Alan said.
"So, we expected it, but we didn't really let that get into our heads."
Hannah competed on Dancing with the Stars as a single woman after ending her engagement to Jed Wyatt, who proposed marriage on The Bachelorette's fifteenth-season finale last year but was caught lying about the extent of a relationship he had prior to the show.

Hannah attempted to dance through a lot of emotions as she was nursing a broken heart.
In addition to her breakup with Jed, Hannah had asked out her The Bachelorette runner-up, Tyler Cameron, during The Bachelorette: After the Final Rose.
But after spending a night together in Los Angeles in August 2019, Tyler quickly moved on with supermodel Gigi Hadid. (Tyler and Gigi's romance ended in October 2019, about two months after it started).
Hannah essentially still had lingering feelings for Peter and wanted him back, but the Bachelor chose to proceed in his journey to find love with his new bachelorettes and leave the past behind him.
"She is a very honest person and I think she'll say [going on Peter's season] did affect her. At the time, I wasn't 100 percent aware of everything that was going on. She told me some things, but I think it happened in Week 2 or Week 3, so it was still early on," Alan revealed to Us.
"Luckily, I was able to help her get through it, but it definitely affected her... We got emotional in rehearsals and it was a very real moment. She realized I was there for her and if she needed anything, I could help her out and she could confide in me."
