So, naturally, Vogue asked her to participate in its "Life in Looks" video series, where celebrities break down their career-spanning outfit choices.
When it came down to her Vera Wang gown for the 2015 Met Gala, Gomez became super honest about body image.
"I fluctuate a lot with my weight," she said. "And I remember this night specifically. I didn't feel good about my body."
"So what was really amazing was that I actually got a chance to work on the dress that fit my body. I had such a beautiful time shaping this dress. I think that we came together and built something really beautiful and something that fit me really well."
"That was one of the moments where I was like, I don't have to be that 19-year-old body shape, because I'm not."
This isn't the first time Selena has opened up about body image.
Back in 2019, Selena spoke about being body-shamed on social media after gaining weight from her daily lupus medication.
Speaking on the Giving Back Generation vodcast, she said, "I experienced body image [issues] with my weight fluctuation for the first time. I have lupus and deal with kidney issues and high blood pressure, so I deal with a lot of health issues. For me, that's when I really started noticing more of the body image stuff."
"In reality, that’s just my truth. I fluctuate. It depends what's happening in my life, it's out of my control and that got to me big time. I think for me, that really messed me up for a bit."
Let this be a lesson to us all: bodies fluctuate, and no one is entitled to talk about anyone else's, alright?
