Demi Lovato Debuts New Video — on Twitter!

It's only November but it's all about Demi Lovato's "Remember December"!

The Camp Rocker debuted the video for the latest single from her album Here We Go Again today on Twitter.

"Remember December video is finally here," she tweeted earlier today. It's early success caused it to be a trending topic on the microblog site, so she posted another item celebrating that news: "#RememberDecember is a trending topic!!! I love you guys SOO much!!"

In the video, which — for better or worse I now can't get out of my head — she appears in a sparkly hooded outfit reminiscent of one of Rihanna's latest couture concoctions. There are a couple other wardrobe changes, including a leather jacket with studded gloves and a girls night look of a gold top and big earrings.

Here We Go Again — Demi's second studio album — was released in July and debuted at #1 on the U.S. Billboard 200. It sold 108,000 copies in its first week. Some of the songs were cowritten by her pals the Jonas Brothers.
