The Bachelorette alum Rachel Lindsay just can't seem to figure Colton Underwood out.

Rachel, who starred on last year's edition of The Bachelorette, apparently isn't a big fan of the charity founder and former professional football player.

In her Us Weekly blog about The Men Tell All this week, Rachel questioned, "Which Colton is the real Colton?"

"Who is Colton? On the show, he was the sweet, boy-next-door but at Men Tell All he was cursing and seemed to have a chip on his shoulders," Rachel explained in her blog.

"This is my issue with Colton. I don't believe you because I don't know who you are or which Colton I am getting."

Colton brought fans on a bit of an emotional rollercoaster during his appearance on The Bachelorette: The Men Tell All for Becca Kufrin's season. Not only did he cry about fellow cast members taking "cheap shots" at his virginity, but he also got angry and sparked conflict and arguments with more than one guy.

Colton also expressed frustration and confusion over Tia revealing her feelings for him to Becca on The Bachelorette.

Although Colton and Tia had a fling in January that ended abruptly due to poor timing, he seemed taken aback that she would want to pursue things further or at least seek closure from him.

"Are you into Tia or Becca? Did you talk to Tia before because you thought she was going to be the Bachelorette? Did you dump her because she was not the Bachelorette? I have so many questions because when I use deductive reasoning, and because I know too much behind the scenes tea, things do not add up," Rachel insisted of Colton.

"As my dad said in describing one of the men that visited him during my Dallas hometown visits, 'The ends do match up.' In other words, something is off."

Rachel therefore believes Colton led Tia on somehow -- or there's at least more to the story than he initially let on.

"We all know I am not a fan of Tia, but Tia is not crazy," Rachel noted of the Arkansas native, who claimed she only kissed Colton and their romance was very brief before Arie Luyendyk Jr.'s season of The Bachelor began airing.

"Tia did not come back to confront Becca just because she and Colton had a few phone calls -- it definitely goes deeper than that. I am personally tired of the downplaying of that relationship to deter us from thinking anything else."

Colton was sent home after his hometown date with Becca seemingly because of Tia's unexpected confession; however, Becca has said on multiple occasions Colton would've gone home regardless of whether Tia came back into the picture or not.

Colton and Tia will be shown reuniting on Bachelor in Paradise's fifth season this summer, which premieres Tuesday, August 7. To read Bachelor in Paradise spoilers, click here.
