Ariel Winter wants you to look at her butt -- like she really, really, really wants you to look at her butt.

The 18-year-old, who is clearly starved for attention and validation, has once again decided to show the world/her 2.6 million Instagram followers every curve of her backside. The most recent offerings are from her Cabo trip with friends -- and we aren't just getting a pic of her rump, we're getting a booty-shaking vid too!

The Modern Family is clearly not bothered by the stressful times in the U.S. -- since she and her pals are partying the day away in Mexico and snapping every moment of it.

The brunette also took to Instagram earlier to post a provocative pic by the pool, showing her and her friend's backsides.

On Oct. 24, the teen attacked body-shaming online trolls: “To those who attack me with body-shaming comments your words are a reflection of what’s inside you, not me. The bullies I encounter online give me the chance to reaffirm to myself, and you guys, the importance of self-acceptance.”

In August, she discussed her penchant for posting posterior pics with Entertainment Tonight, explaining, “Everybody is so hyped up on the fact that I post photos where my butt’s out. It’s a butt. Everyone has a butt. I don’t think it’s crazy.”

We don't think it's crazy, but we do think it's kind of sad ...
