Tisdale definitely isn't one to let comments on social media bring her down. The singer laughed off a recent braless wardrobe malfunction while speaking to ET last year. 

"I literally saw the pictures on Twitter start coming up, and I literally started laughing," she said. "I was like, 'Of course this would happen to me!' Like, of course. But it's just one of those things that you have to laugh at. It's so ridiculous."
