NC because this is very outing.
About two weeks ago, DH and I attended a wedding where DH was the Best Man. The bride went a little bit "bridezilla" in the build-up to the wedding - including quite a big argument where she was insisting to her DH that the bride should get a veto on any wedding decision and was insisting that she got to choose the suits). We're not in the UK so Covid restrictions were different so around 100 people in attendance.
On the day, the band contacted the couple to say that there was some issue (it was illness related but not sure if it was Covid) and they couldn't be there. DH is a musician with an audio background - he spoke to the Groom offered to sing and play guitar for their first dance and a few other pieces. I also sometimes sing with DH (I'm not a professional singer) so I did some backing vocals for the songs. I thought it was quite nice and went quite well all things considered - it was also quite a lot of stress to try and sort out on the day of the wedding to go home and get kit and get things set up without anyone really being aware or missing any part of the day.
I've just been messaged by the Bride today to say that she's really hurt that I made "her day" all about me "by stealing the limelight". I also wore white shoes (with a navy dress) and she's said it was "totally inappropriate and really nasty". I feel like this is completely absurd - I only sang the backing vocals and, of course, all eyes would've been on her! I understand not wearing white to a wedding but I feel like it's just my shoes - am I wrong here?
Should I apologise just to keep the peace and prevent anything being awkward with DH and his best mate? Should I ignore entirely? Should I respond and defend myself? Or was I in the wrong and should I apologise?
