One of the ladies in question -- who's now copping to being part of the group that got chastised by Lambert -- posted two pics she says were being taken right before the country singer paused her show over the weekend to give them a piece of her mind.

As you can see ... there are six women pictured here, who are at the foot of the stage, with ML right behind them -- who's trying to get the show on the road. More importantly, all of 'em are standing ... and from the looks of it, apparently blocking the view of others.

On its face ... it sure looks like they, perhaps, might've been a distraction -- that's certainly how Miranda felt anyway, proven in her mini tirade ... which her audience had backed.

Miranda actually caught flak for this ... as some felt she'd overreacted to what many presumed was a couple of girls firing off some low-key selfies during her set. However, that's clearly not the case -- it was a much larger gathering ... and a bit of a photo shoot, it seems.

BTW, the lady who posted these definitely thinks Miranda was in the wrong -- evidenced in her caption.

She writes, "These are the 2 pictures we were talking when Miranda Lambert stopped her concert and told us to sit down and not take selfies 😱." She's echoing what many said about Miranda's response -- mocking her, essentially -- but now ... ML might be vindicated!
