Britney Spears giveth, so she can also taketh away -- which is exactly what she just did -- 2 weeks before her monumentally important court hearing.

The singer deleted her IG page Tuesday ... with a generic "Sorry, this page isn't available" message that appears if you click on her handle.

There was no heads-up from BS either, but, we've got an explanation as to why -- sources with direct knowledge say she wanted a break from social media ahead of her court hearing later this month.

As it was put to us, Britney wants to keep a low profile. As for why, our sources say there was concern in Britney's camp that she was too "out there" with some of her posts, especially the topless ones, and that might not sit well with the judge.

At the risk of possibly reading a little too much into the latest twist, the only thing Britney has on the table for the Sept. 29 hearing is to remove her dad from the conservatorship. Her social media posts shouldn't affect that decision. You gotta wonder ... will she formally make a play to end the conservatorship as well? That would be a more direct reason to 86 her social media account.

Still, it's a little bizarre ... because she'd just announced a couple days ago she's getting married to her BF, Sam Asghari.

Here's hoping she comes back soon.
