Ariel Winter has contoured her bottom.
The 'Modern Family' star shared a picture of a make up artist working on contouring her bare bottom for a photoshoot.
She captioned the photo: ''BUTT really, don't miss a spot. #secretshoot #embraceyourcurves (sic)''
The 18-year-old actress is incredibly proud of her body and says she has her co-star Sofia Vergara to thank for helping her to embrace her curves.
She said: ''I was very insecure when I was younger because I did grow up in the public eye.
''But then as I got older, I was surrounded by people like Sofia Vergara, and people who were curvier like me and were proud of it. And who were showing it off. That really helped me to move forward and be proud of my body.''
Ariel has regularly been criticised for posting sexy snaps to Instagram but she doesn't understand why people make such a big deal about it.
She added: ''I don't really think I'm telling myself, 'You should post this, you shouldn't post that,' I feel like I'm just having fun. I like my fans to see what I'm doing. 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.
''It's like, 'Let me live! I'm enjoying my life, you're enjoying your life, you should be posting your butt if you like it, too!' I'm not going to fight with someone on my Instagram that tells me they don't like my outfit or I should put my butt away. I'm sorry you think I should put my butt away, but just unfollow me.''
