Britney Spears Ends March By Thrusting On The Beach

Britney Spears -- the 1990s heartthrob who's frankly been pretty weird ever since -- hit the beach to end the first month of spring in style.

The singer capped March with some sand aerobics at the water's edge, filled with a little thrusting, a little modeling, and what appears to be a weird crawl of some sort aimed at the camera.

It was peak Britney, except she's now 41 and trying to recapture the magic. I don't know, you tell me ... does she still have it?

Britney Spears goes on weird Instagram bender

A lot to digest there. Ton to break down. Let's start with this ...

There's a lot of rolling around in the sand here. I mean, it's a bit much. I know there's only so many different poses you can do at the beach, but that's why you make 10-second videos. This bad boy just keeps going and going and going, and I feel like it gets a little repetitive towards the end.

Which, by the way, NEVER comes. I just kept waiting for the video to end, and then BAM -- more Britney Spears going spread eagle in the water.

Anyway, I guess I'm just happy Britney's happy? I know there was the big #FreeBritney movement for years, and then she got freed (I think?) but then went kind of nuts again, right?

I don't know -- I can't keep up and don't want to.

Scrolling up and down here Instagram, though, Britney seems to be on somewhat of a bender right now. She also posted five -- FIVE! -- videos since yesterday, and they're all of her just randomly dancing in different clothes.

This one, in particular, was a wild few minutes. Not exactly the Britney Spears I grew up watching on MTV, but I can still dig it.
