The Countdown Is Over: See Who Made PEOPLE's Most Beautiful List!

Introducing 2016’s World’s Most Beautiful star! Despite being timeless, ageless … and well, beautiful, the Mother’s Day actress opened up to PEOPLE that she used to be teased for having “a bubble butt,” an asset she now embraces. “Now people are paying money to get things injected. Like we’re sitting here dying over squats and I’m like, ‘Wait, what’s the trend?!'” she adds. “I think [I’ve accepted] just my body in general. I used to be such a little round thing, now I’m just like my body is my body so I’ve embraced things overall.”

It’s true what they say: Self-confidence truly blossoms as the years pass – at least that’s what the Oscar winner has experienced. “Sexuality and femininity is an accumulation of age and wisdom and comfort in your own skin. I feel better – so much better now than I ever did in my twenties,” Witherspoon tells Glamour. “I am calmer; I know who I am. And as a result I feel much sexier.”

When it comes to confidence, the Modern Family actress has it down, opting choosing to show a little skin for a boost. “Confident people have a way of carrying themselves that makes others more attracted to them,” Vergara tells Shape. “Latin women are very comfortable with their bodies and their sexuality. We aren’t afraid to show that off a little bit more.”

The Scream Queens star is a force to be reckoned with – not only when it comes to her successful acting and singing careers, but also with her inherent need to voice her opinion, particularly when it involves talk of her sexuality. “I don’t feel the need to define nothin’ to nobody, because I’m always changing. Why say that I’m this or that when I might not be tomorrow?” she tells PEOPLE of her thoughts on labels. “I’m gonna follow my own feelings and my own heart.”

What makes the “Same Old Love” singer beautiful? Aside from the obvious, Gomez is also refreshingly honest – especially when it comes to body image and self-confidence, issues only a handful of stars have addressed in the past. “It hurt my feelings because I never experienced that before, but I didn’t want [that] to be my story,” Gomez tells InStyle UK of being the target of body shaming. “So I said, ‘I don’t care what you think’ … I’m learning that you can be comfortable and still look beautiful.'”

She’s been an on-screen regular since the tender age of four and has made quite a name for herself in the 30 years since. Despite starring in a slew of different roles in TV and film, Good reveals one thing that has remained constant in her life: Her feelings of self-worth. “I’ve always had that kind of spirit where I love me, and I accept me, and I feel beautiful, and I feel sexy,” she tells MIMI. “And I’ve felt that from a very young age.”

It’s been over a decade since the world was introduced to the country music star, who won American Idol in 2005. Since her coronation, the singer has racked up countless accolades, including multiple Grammys, a Golden Globe nomination and the honor of starring in NBC’s first-ever live TV adaptation of The Sound of Music Live. The reason for all her success? The singer credits a positive mindset. “Talking yourself up is a big thing,” she reveals to Parade. “People might think you are nuts talking to yourself and telling yourself how awesome you are, but it helps to say, ‘I am strong.'”

Despite being in the entertainment industry for well over a decade and boasting plenty of acclaim through the years, the triple threat (she’s a singer, actress and executive producer on her family’s reality show, Christina Milian Turned Up) is quick to reveal that her self-confidence doesn’t come without hard work; in fact, the star credits her rigorous workout routine. “You don’t have to be like anyone else,” she tells Shape. “We’re all human, we have our flaws and it’s OK. Working out is probably one of the best things you can do. It can be in the form of walking and talking to somebody. I find when I’m a little down on myself it feels good to exercise.”
