Taylor Swift is not dating Joe Jonas of the Jonas Brothers.

"We're all friends," she told PEOPLE.

She recently received her diploma in the mail and she's beaming with pride.

"Graduating high school is really, really cool," she says. "I'm so proud of it because I stopped going to high school in 10th grade, but I started home-schooling."

"It's really good to know you don't have to give up on your dreams to graduate high school, and you don't have to quit your education to live your dreams," says Swift, who was recently also named Goddess of Summer by Venus Embrace razors. "It's really cool that you can do both."
