(tl;dr, AITA for uninviting a friend from my wedding for consistently telling me, and others, that my marriage is a huge mistake)

Let's start with the good news -- I'm getting married next year! I'm thrilled, my fiancé (28M) is thrilled, we're stupidly in love -- all that good stuff. We're planning a large wedding in the city we both live in.

Now, for the hard part. Between sending out the "save the dates" and invitations proper, my friend "Anne" made it very, very clear that she thinks my impending marriage is a huge mistake. 

My fiancé and I got engaged very quickly (after &lt; 4 months) -- which I get would give people pause -- but almost everyone who knows us (including our families) has basically gone: "yep, you two are perfect. We support you." Except Anne.

I've recently learned that Anne has repeatedly gossiped within our friend group about how we're "never going to make it", &amp; how we're total idiots for getting engaged so soon. Things came to a head a few weeks ago when Anne got very drunk at a party and loudly announced, right in front of me, that I'm "irresponsible" and make "impulsive decisions," and that my marriage was stupid and irresponsible. She apologized the next day, blaming her drunkenness, and said that she "didn't mean" it, but the damage was done. (Complicating things is that Anne is very close friends with an ex of mine, also in our social circle, whom I went no contact with after he behaved horribly to me when I started dating my now-fiancé. I strongly suspect that my ex is spinning narratives about how this wedding is a huge mistake, or a sign of my emotional immaturity, and that she's bought into that narrative. Anne's closeness with my ex has hurt me for a while -- she's blown off multiple plans with me while hanging with him (platonically) regularly -- but I'd still tried to make the friendship work: inviting her to my engagement party (she attended) and sending her and her bf save-the dates.

But now, the idea of Anne attending my wedding makes me feel sick. I want to spend our wedding surrounded by people who love and support us, not stressing about people who've made it clear they're aching to see us fail.

But -- etiquette says that once you send out STDs (or invite someone to the engagement party), it's impossibly rude to uninvite them. Would I BTA if I did so? And, if I decided to uninvite them, should I tell her directly that I no longer wish her to come, or just quietly leave her off the final invitation list. (Or should I ask my MOH, who knows her, to be an intermediary here?) I don't want to be rude -- or to get a reputation in my wider friend group as a Bridezilla. I'm not too concerned about salvaging a close friendship with this girl but I also don't want to, like, create a giant dramatic social battle within our extended friend circle.
