In the apology -- which MTV.com posted a screen grab of -- West said "I'm in the wrong for going on stage and taking away from her moment ... I will apologize to Taylor 2mrw ... I'm sincerely sorry!!!! Much respect!!!!!"
We're not sure how long the post was up, but it's no longer on the site.
Beyonce, who looked mortified when West rushed the stage to give her props, made good in the show calling Swift back onstage to give her a chance to make a proper acceptance speech.
