Demi Lovato: No More Public Relationships For Me!

Demi Lovato is speaking out about her former relationship with Joe Jonas one last time. This time, she says she wishes she'd made more of an effort to keep it private!

"I learned my lesson," says Demi. "It's not very much fun when you break up in a public relationship. So, maybe next time keep a secret."

Interesting, seeing as Joe Jonas showed up to Demi's 18th B-Day party today! On that note- Happy B-Day Demi!
