"I have reasons for why I am the way I am, I have a very bold personality. I'm ... a lot to handle," she told Higgins during a late night discussion.
"I was very dorky looking when I was a kid, can I tell you one picture? One picture I had these double bangs ... My brothers on the school bus would be like, 'Oh, you're not my sister, I don't know you' ... so, this is a lot for me to tell you right now."
After her confession, a tearful Morris was interrupted by another contestant, and she headed into a room on her own without realising her microphone was still on.
"The insecure Lace came out, and the Lace I promised myself that I would not be came out ... oh my God, I feel so stupid," she muttered before bursting into tears.
Her antics have earned her headlines like this from the New York Post: "Lace is the train wreck we love to hate."
Despite her wayward emotions, Higgins is a fan of Morris, who is yet to be eliminated. He wrote in a blog on People.com that he's a big fan.
"I know Lace and my decision to keep Lace has been the subject of a lot of discussion, but I saw in my conversations with her what a sweet and sincere woman she seemed to be.
"So despite some hiccups on night one, I viewed this as a new day and a fresh start with Lace."
