The "Zombieland" star took to IG, Sunday night ... telling fans she had exchanged vows with her now-husband over the weekend. She wrote," 01.28.23❤️💍❤️ married my bestest friend. @richruski" .. while sharing a photo of the two at their wedding.

Before that, she made a post showing off THAT finger with her dazzling engagement ring and a wedding band ... saying "ya girl got married y’all."

Her hubby Ira also proudly posted his bride, sharing a pic of them on their big day saying ... "Love my other second half ❤️ @abbienormal9".

The newlyweds have been romantically linked since 2017 when they first started dating.

Ira popped the big question last February, and Abbie had a pretty funny reaction to his proposal when she posted it ... her caption read, "I was like, 'duh. #engagedyall".

Since then, Abigail has shared some of their special moments with fans -- on New Year's they posed for a photo, as they rang in 2023 together.
