In doing so, Tom had to escort Ellen, her mother and wife Portia De Rossi throughout the night from the red carpet to the Dolby Theatre and the post-ceremony Governor's Ball.
"I'm holding their hands and walking them through individuals and large groups of people. Ellen is the one person that I've been assigned to – and I've been assigned to quite a few celebrities – that has never taken the time to say hi to me," Tom claimed.
During the night, he said he spent "a lot of time" with Portia, who was "very pleasant and carried on a conversation."
"It started going negatively when she introduced me to Ellen and Ellen pretty much just gave me a side glance out of her eye and didn't even say 'hello,' or 'thank you for protecting my mother, my wife and me,'" Majercak continued.
"It was very cold and it was very sly and it was actually kind of demeaning in the way that she treats people other than those who are in her circle."
Ellen's rep did not respond to Fox for comment.
Tom said he stood closely to Ellen at her table at the Governor's Ball. Ellen was allegedly chatting with celebrities who ONLY pre-approved to come to her table, he admitted.
Tom admitted that the recent allegations against Ellen by her former staff and guests prompted him to speak his truth.
"It's bugged me for years," he shared. "I see this person come across as being very enlightened and positive and awesome and everybody loves her and is in awe and that's really not the case when you meet her in person."
Tom acknowledged that hosting the night wouldn't be easy for Ellen, first believing that he was the "brunt of her frustration" because of how overwhelming the job was. But he claims it's "no excuse."
"When you see her on TV, people fall in love with her but it is a false facade and bravado," he continued. "You start hearing these stories and I was like, 'Man, there's got to be more to this.' She's not the person she portrays to be that she's playing off of society. That's my opinion."
"I can absolutely see through interacting with her first-hand that she doesn't care about anybody else as long as she's getting what she wants," Tom concluded.
"People are starting to see her true self and that really lends to the support of what my initial thoughts of her have been over the last six years."
