Kaia Gerber opts for jeans and tank top as she votes for the first time with mom Cindy Crawford

Kaia Gerber has grown up before our very eyes, celebrating her 18th birthday last September.

And the model/actress recently experienced another important milestone, when she exercised her civic duty.

She opted for a classic American look Friday in a cropped white tank top and faded high-waisted jeans ripped at the knee, as she voted for the first time in Malibu with her parents.

The 19-year-old teased her taut midriff and a black bra under her top, finishing the look with a black face mask, navy blue Chuck Taylor All Stars.

She hung a pair of black sunglasses from her shirt and carried a cognac leather handbag over her shoulder.

Kaia also wore an ‘I VOTED’ sticker on her chest and carried a sample ballot, as she left her polling location with supermodel mom Cindy Crawford, 54, dad Rande Gerber, 58, and a friend.  

She later took to Instagram with a selfie, displaying the sticker on her face mask, captioned: ‘i voted for the first time today and it felt really good. i’m so proud to be part of the election, because it’s become so clear how much power young people have to push this country towards progress — as long as we participate.

‘i don’t want to grow up in a country that is going backwards. the past four years have shown us how much damage can be done when our leadership prioritizes property over people, tolerates racism, and ignores science. 

‘if you’re not sure if you want to vote, i ask you to consider who and what will be most affected if you don’t. please vote even if it sounds like a headache. do it with empathy, do it with love, and do it with reason because it matters’

The brunette beauty also posted a maskless selfie from the car to her Instagram Story, wearing the sticker on her nose, before posing in front of the polls.

She wrote: ‘I voted in person today and it was so easy! socially distanced polls and no lines or groups of people. you can too!’ 

Kaia has been urging her 6million followers to vote, taking to Instagram last week after having her wisdom teeth taken out.

She gave a thumbs up, as the dentist held up her pulled teeth in the photo, captioned: ‘we don’t need wisdom teeth to vote wisely’

The Vogue Italia cover girl also had a conversation via Instagram Live earlier this month with Democratic candidate Joe Biden’s granddaughters Naomi and Natalie.

She told them of why she’s voting Biden/Harris: ‘I think, for me, it’s mostly just feeling heard about a lot of the issues. I think climate change, as you were saying, Natalie, that isn’t something that is going to directly affect the older generations who are in office. 

‘So to feel like they’re still fighting for you and the younger generations—that’s really important, because that’s going to affect us and our children and their children. And it’s something that just can’t be ignored anymore.’
