Colton, 27, weighed in on the rumors Jed -- one of Hannah's Final 4 bachelors -- left his then-girlfriend Haley Stevens in March to film The Bachelorette and promote his music career with the intention of returning home after the show and resuming their romance in Nashville, TN.
"My thoughts are if he had a girlfriend and if those articles are true and everything, which it seems like it, it's messed up," Colton told Access.
"I think Hannah will handle it the way that is best for her and her relationship with him. It's not mine. I stay out of the drama now because I'm happy and in a relationship, but I just pray that she makes the right decision and does what makes her happy."
Jed was shown admitting to Hannah during a previous one-on-one date in Newport, RI, he had joined The Bachelorette for the platform and to boost his music career, but all he's been getting is bad publicity because of this scandal.
"I am so supportive of her as a person," Colton said of Hannah.
"I am hopeful that she's going to be happy at the end of this. Who knows if that means she's with anybody or not, but I know that Hannah is an incredible person and she deserves love."
Haley claimed in multiple interviews last month she had stayed with Jed -- whom she allegedly met in October 2018 -- once he was cast on The Bachelorette because he had given her every reason to believe they'd continue dating once the show was over.
After Jed received the call in February 2019 he had been chosen to join The Bachelorette cast, Haley told People she and the country singer took a romantic trip to the Bahamas, where they said "I love you" to each other for the first time.
Haley said Jed was always "so reassuring" when she'd express concern over the fact he might end up seriously dating another woman and falling in love. He also allegedly called her when his plane landed in Los Angeles before filming commenced.
"He said, 'I love you, and I'll call you when I get back,'" she previously told People, adding that she had attempted to follow Jed's Bachelorette progress online.
"I was following along on spoiler accounts, trying to figure out when my boyfriend was going to come home... [Jed] said he only wanted to be Top 5 [bachelors]... to be a major player so that it would be beneficial [to his career]," Haley told People last month.
Haley was therefore "baffled" when Jed returned home to Nashville after filming and allegedly "ghosted" her. Haley said when she had bumped into Jed at a music venue in early June, he offered her no explanation.
"He loved me, but he didn't have enough respect for me to have that tough conversation," she told People.
Reality Steve spoiler blogger Steve Carbone also claimed on an episode of his podcast in late June that Jed had allegedly slept with another woman while dating Haley.
"She showed me everything... this was I believe 10 days before you left for the Bahamas, he slept with another woman," Carbone had told Haley on the podcast, according to E! News. "And I have the text messages to prove it."
After weeks of receiving backlash on social media in light of this scandal, Jed finally broke his silence via Instagram on Monday.
"I ask that you please understand how much the actions being taken towards myself, my family, the men on the show, and above all, Hannah, are affecting all of our mental and physical health," Jed wrote.
"It goes beyond what is said online. Threatening letters and phone calls have been sent to our homes. My parents and sister are being verbally attacked in public. I beg you to remember what seems like a harmless action is damaging to real people."
