"He loves to drink. He's like a 30-year-old man child. He goes to music festivals every weekend. He's, like, drunk every night. He's literally always partying, so I was not at all shocked that he got wasted and got involved in some drama," Lexi told TMZ.
"But it doesn't sound to me like he was predatory or an aggressor."
Production on Bachelor in Paradise's fourth season was suspended last week after a producer filed a complaint with Warner Bros. over alleged sexual activity that made her "uncomfortable" between DeMario and Corinne that occurred in a public pool at a Mexican resort, according to prior reports.
An investigation was launched because the producer was allegedly concerned DeMario was taking advantage of Corinne since she appeared too drunk to provide the bachelor with consent for their PDA.
(However, sources told E! News that the producer never actually witnessed the sexual act in question, nor did she view recorded footage of the events that transpired prior to filing her complaint).
"The show absolutely values the primacy of consent, and this instance it appears as though conduct allegedly occurred without the proper consent having been given," a Bachelor in Paradise source recently told People, adding that the situation is "incredibly difficult and complicated."
However, sources close to DeMario told TMZ earlier this week that Corinne was the aggressor on that first day of filming and actually initiated kissing and foreplay with DeMario on Bachelor in Paradise, which ultimately led to oral sex in the pool.
Reports have also surfaced Corinne had a boyfriend back home while filming Paradise and so she was ashamed to have hooked up with another guy.
"It sounds like the situation got messy and she kind of wanted to cover up for herself," Lexi told TMZ.
"All the conversations I've ever had with [DeMario] when he's drunk, he's always very fun and playful and belligerent. I've never seen him be aggressive or like domineering, or anything like that. It sounds to me like everybody was drunk, but I really don't think he would take advantage of someone who was, like, unconscious and unable to consent."
Lexi continued, "I don't think his character has been ruined, but I definitely think it's obviously super harmful to someone's life if rape or assault claims are being brought against them."

With that being said, Lexi doesn't exactly have great things to say about DeMario.
"I truly hate him," she confessed to the website. "I think he's a sh-tty guy, he's self absorbed, and he's not a good person. But I really don't think he would do something like this. I really don't."
Bachelor Nation was first introduced to Lexi when she showed up on one of Rachel's group dates -- when the guys played a game of basketball in front of Kareem Abdul-Jabbar -- earlier in the season to confront DeMario about his alleged betrayal and lies.
Lexi claimed to Rachel that DeMario had been dating and having sex with her right up until he cut off communication -- with no alleged explanation -- several days before he appeared on Nick Viall's The Bachelor: After the Final Rose special to meet and get to know Rachel before filming for The Bachelorette commenced.
Lexi said DeMario still had the keys to her apartment and never stopped texting her. DeMario tried to muster up an explanation that made sense for Rachel, saying he dated the "psycho" on and off, but Rachel thought he was being dishonest and immediately eliminated him from the competition as a result.
DeMario has therefore been involved in two Bachelor scandals within the last several months.
In regards to the current situation involving Corinne, the bachelorette released a statement on Wednesday saying she is "a victim" and has been dealing with "physical and emotional trauma" from the incident that occurred while filming Bachelor in Paradise. Corinne said that "as a woman," this is her "worst nightmare."
However, multiple Bachelor in Paradise sources allege Corinne was alert and "very with it" while hooking up with DeMario, TMZ reported.
In a statement DeMario released Wednesday night, he said he doesn't appreciate that his character has been "assassinated with false claims and malicious allegations."
"I will be taking swift and appropriate legal action until my name is cleared and, per the advice of legal counsel, will be seeking all available remedies entitled to me under the laws," he said.
Warner Bros. said in a recent statement the company is looking into "allegations of misconduct" on the set of Bachelor in Paradise, and once the investigation is complete, "appropriate responsive action" will be taken.
