BritneySpears.com used to be nothing but a half-naked picture of Britney with white gloves and an "under construction" sign that was up while Miss Spears was, um, out of emotional, mental, physical sorts. But with a No. 1 single in "3," a new greatest-hits album and a booming tour, both the singer and her website -- which is now in blog form -- are in tip-top form. Find feeds for her Twitter, her Facebook and up-to-the-minute news on all things Britney. Don't miss: seeing your own comments to the news posts on the right-hand rail of the site.
