"Today I turn 21! Holla!!! But just because I'm now the legal drinking age, doesn't mean I'm going to start throwing 'em back. I don't plan to start drinking," Zendaya shared on her website. "My life is too stressful to need help with relaxing by having a cocktail."
"This industry is way too nuts for me to not be in control of myself and my decisions, so I just don't want to introduce drinking!" she continued. "Plus, I don’t want drinking to become a vice. Why try something if you don’t need it?!"
While Zendaya has opted to stay sober, her Spider-Man: Homecoming co-star, Tom Holland, took to Instagram to wish his friend a happy birthday and tell her he'll have a drink in her honor.
"Thinking about how to get taller ? Happy birthday mate. Miss you and I'll have a drink for you. #21stbirthday," Holland wrote alongside two promo pics of them together.
The day before turning 21, the Disney star also announced her annual birthday project. This year, Zendaya is partnering up with Convoy of Hope to help those affected by Hurricane Harvey.
"With the devastation of #HurricaneHarvey I knew what this year's birthday project had to be.. I called my friends at @convoyofhope to help. Here's how you can get involved too. No contribution is too small, and it's super easy to help," she wrote alongside her Instagram video.
