Gina Rodriguez on Haters and Why She's Excited to Have Britney Spears Join Jane the Virgin

"I don't attach myself to things I don't believe in. I wanted to support this product and Crest, because the truth is I love smiling. How much better in life do you feel when you're smiling? I feel it, like I really feel it. I had a little bit of a sad day this week, and my director for Deepwater Horizon said, 'Why aren't you smiling? Smile! You're always smiling. You're bringing this place down. You're the one that's supposed to bring the smiles.' I grew up with Crest in my household. I love that I was able to partner with them. And I love this whitening product, because it is supersimple. I need simplicity in my life. I travel with it and use it every time I brush."
