Christina, a 26-year-old content creator from Nashville, TN, arrived at The Bachelor mansion on Night 1 in a party bus, and she was noticeably loud, outgoing and outspoken during the rest of her time on the show's 27th season.
Zach called Christina "fun and spicy," but she rubbed her fellow bachelorettes the wrong way with her candid remarks, and some viewers accused the bachelorette of being drunk and messy while filming the show.
Christina therefore took to Instagram on Monday, February 6 addressing all the criticism.
Christina posted a funny video compilation of herself being silly, goofy and playful. She captured moments of herself shouting, dancing, prancing, and even banging on a drum.
"Not that I have to explain myself... BUT. There's been some speculation that I'm 'dRuNk AlL tHe TiMe'... so I just wanted to make a little compilation of some videos taken of me over the past few days. This is me completely sober," Christina wrote alongside crying-laughing emojis.
"I realize my personality isn't for everyone... I'm 'a lot.' Life is short, and I strive not to spend it dulling my personality to please others. So yes, I do have goofy, chaotic energy, which sometimes can be annoying."
But Christina said she is proud to be herself -- and she's loved for it, by many.
"By being myself, I'm able to find my closest, most genuine friends and set what I believe to be the best example for my daughter," Christina continued in her post.
"I want to show her that she never has to dim her light for the sake of others' opinions," she concluded.
Christina was the envy of her competition when Zach brought her home to meet his family during the first one-on-one date of the season.

But Christina made the situation worse by constantly talking about the solo date and her supposed strong connection with Zach.
"Respectfully, if I hear 'one-on-one' [again], I might lose my mind -- not that I don't care or I'm not happy for you, but we know," Brooklyn Willie complained during the football group-date afterparty.
"We've heard about your one-on-one, we've heard that you met his family. I almost feel like it's malicious."
And when Zach gave Charity Lawson the group date rose, Christina admitted she was "confused" by his decision.
"I'm mad it wasn't me. Duh!" Christina was shown saying.
When Brooklyn and Kat Izzo confronted Christina about her eyebrow-raising behavior, the single mother explained how she was just keeping it "100" and being truthful with them about her feelings.
"Christina definitely hijacked that moment from Charity like she's trying to intimidate and manipulate and be calculated. I'm just sick of her B-S," Brooklyn vented to the cameras.
And then during the pool party that preceded the third Rose Ceremony of the season, Brianna Thorbourne warned Zach that Christina had made Charity and herself cry.
Brianna claimed Christina had made women in the house feel insecure and fearful of opening up and being their authentic selves. Brianna led Zach to believe that the dating environment didn't feel safe for his bachelorettes due to Christina's presence.
"I'm feeling such a strong connection with Zach, and I know he feels it too," Christina explained in a confessional.
"I can see him being a stepdad. I feel like I'm just hanging on for my life. I think he trusts me, hopefully, but how do you say three girls -- and one who went home because of me -- are lying? It just doesn't look good for me, and it really hurts."
Brianna quit the show due to Christina's antics but also because she and Zach were not feeling an easy, romantic connection with each other.
Although Christina insisted to Zach that she never meant to hurt anybody and thought she had squashed her beef with the other bachelorettes, Zach denied her a rose at the Rose Ceremony.
