Ariana Grande, who apologized in July for anti-American comments heard on security video from a doughnut shop where she had also licked pastries for sale on a counter, spoke Tuesday of what the incident had taught her.

"First of all, I mean, my behavior was very offensive and I apologized," the 22-year-old singer-actress told "Good Morning America" co-host Amy Robach. "There is no excuse or there is nothing to justify it. But I think that as human beings we all say and do things that we don't mean at all sometimes. And we have to learn from it. I mean that's part of our process. We have to learn from our mistakes and that's how we grow."

When asked specifically what she had learned, Grande, who was promoting her new fragrance "Ari," said: "I think one of the biggest things I learned from that was what it feels like to disappoint so many people who love and believe in you, and that's an excruciating feeling. And you have to remember that your words, your actions, have ramifications and you have to really think about what you're about to say and do because it's important. It's important to so many people."

In the video posted July 7 at TMZ.com, Grande and one of her concert tour's backup dancers are in Wolfee Donuts in Lake Elsinore, California, where they appear to lick unsold doughnuts on two trays. When an employee brings out a tray of large pastries, Grande says, "What the [expletive] is that? I hate Americans. I hate America."

The Florida-born Grande quickly issued an apology statement saying, "I am EXTREMELY proud to be an American and I've always made it clear that I love my country. What I said in a private moment with my friend, who was buying the donuts, was taken out of context and I am sorry for not using more discretion with my choice of words."
