Never looked better: The actress has a ball as she shakes her stuff in a white tank top

A whole new Amy: Schumer appears slender as she shows off her naked tummy

Amy looked fantastic as she danced around on stage, not only twerking but also throwing beer on her chest.

Amy is supposed to be a less attractive girl in the movie, but in this scene she looks to be in great shape.

At one point she shows off abs as she does her moves in a white top and red shorts.

And she did this too: Her character is so confident she pours beer on herself

Naughty time: She even slinks up to a man, thinking she is the sexiest thing he has ever seen

The clip begins with her saying in voice over that only the pretty girls get noticed.

She is seen being blown off by bartenders in a bar then talking to her pals about how more simple girls do not get ahead.

Then she is spinning in a class. That's when she falls and hits her head. She comes to and looks in the mirror.

She made it too: Emily Ratajkowski also pops up in the trailer, though it's not know what her role is in the comedy

Obviously something shifted in her brain because now she thinks she looks like a supermodel, like a Kendall Jenner or Gigi Hadid.

Next Amy is seen in a mini skirt strutting into an office building as she displays her new confidence.

The star also meets with Naomi Campbell and Michelle Williams to talk about possibly modeling.

Along the way she also talks to Emily Ratajkowski.

And when a man asks for her number in line as she picks up her dry cleaning she thinks he is asking for her phone number.

The message of the movie seems to be it's not what you look like but rather how confident you are.

I Feel Pretty is set for theaters June 29, 2018.

The trailer was released after Schumer proved she'd go above and beyond for the sake of comedy during her appearance on Ellen Thursday, where she donned a frilly pink baby outfit.

While the star embraced her inner child she wasn't afraid to exhibit her bare legs and diaper-clad bum while bending over host Ellen DeGeneres during the daytime show.

What a babe! Schumer went above and beyond for laughs, donning a frilly pink baby outfit during her appearance on Ellen Thursday

Amy came out following an earlier segment where Ellen rated babies for the audience.

The very big baby's outfit came complete with a bonnet, pacifier, and oversized bottle.

Explaining her look, the star said: 'It's actually not about how I'm dressed, this is a full lifestyle change.'

Then she leaned in as if telling a secret, saying: 'Everyone in Hollywood, obsessed with youth.'

After remembering it was time for a feeding, Amy had Ellen spoon feed her some mush.

Of course, being a baby, the star needed to be burped after so she leaned over the talk show host to expose her diaper covered backside while Ellen tried to contain her laughter.

Schumer switched into a more age appropriate outfit, donning a black pussybow blouse and well-tailored trousers to debut the trailer for her new film I Feel Pretty.

In the film, Amy plays a woman who struggles with self confidence but suddenly finds herself thinking she's the most beautiful and amazing woman in the world after suffering a fall.
