So we know this is obviously aimed at us and I have two thoughts on this;
1) I think this is a reference her trying to wind us up about being engaged. I don't think her "engagement" is genuine, because if it was she would have made it very clear that they're engaged and would have made a post about how this one treats her right, how amazing he is etc.
Instead we got a vague post with emojis. She did that for plausible deniability. I know she's unhinged but I don't think she's "get engaged after a month" unhinged.
2) Regardless of whether point one is correct or not, why is she giving ANY thought or time to the people gossiping about her, while she's on holiday? I barely remember to check my social medias while I'm on holiday, but here she is, she MUST let us know how unbothered she is.
Chelsea hun, go and enjoy your life. Stop caring about what we think about your life. Stop referencing us. People who truly don't care don't feel the need to announce that they don't care every week.
