We heard rumors that Demi Lovato and Wilmer Valderrama have split, and Demi took twitter to pretty much confirm the rumor. She wrote “The smartest thing a woman can ever learn, is to never need a man.” and then a quote by Marilyn Monroe: “A wise girl kisses but doesn’t love, listens but doesn’t believe, and leaves before she is left.” After tweeting all of this, Demi realized it might not be the smartest idea since the whole world can read it. This weekend she wrote “Twitter break. It’s for the best actually. Who allows me to have this thing anyways?!!! I just get myself in trouble! Haha. Anyway… BYE!” Aw, we loved reading your tweets Demi! We hope you’ll be back ASAP! (celebuzz)
