Justin Bieber’s imperial reign over the Twitterverse remains uncontested for the fourth straight week, thanks to the release of his new album “My World 2.0″ and the recent arrest of his manager.

Our friends at What The Trend have crunched the numbers for us, and provided a week-long measure of what’s been hot on Twitter. Because this is a topical list, hashtag memes and games have been omitted from the chart below.

“Follow Friday” (at number two) and “Music Monday” (at number eight) make their regular appearances as staple, user-created Twitter memes. Third on the chart this week is “Health Care Reform,” as the U.S. House of Representatives voted in favor of a bill to overhaul the U.S. health care system and provide coverage to millions of uninsured Americans. The controversial bill was signed into law by President Obama on March 23rd, though the Congressional process was not without its drama.

A new meme, “I [heart],” made its way up the charts, as people tweeted about their favorite things in any category. And “March Madness” (at number five) rolls on this week as a number of upsets have been rocking basketball fans’ NCAA brackets.

It was Twitter’s birthday last week, and the name of the social network itself came in at number six, with people tweeting their love for the service. Our own hashtag, #thankstwitter4, made the rounds, as we asked users how the micro-blogging site changed their lives. You can read 140 of the best responses here.

Michael Jackson jumped back into the week’s trends at number seven, as fans tweeted about their memories of his music and performances. News about the ongoing investigation into his death also spurred some Twitter buzz.

Two entertainment items round out the week. The Korean boy-band Super Junior saw another surge in fan tweets after the group performed in Malaysia. And coming in at number 10 is a strange discussion about the Oxygen network’s show Bad Girl’s Club. Natalie, one of the show’s stars, apparently has a chin so unusual, it warranted a week’s worth of chatter on Twitter.
