Justin Bieber remains an immutable force of Twitter trend power, taking the top slot again for the third week in a row. Tweeters also showed their love (and/or disdain) for a number of other pop singers, and celebrated a few holidays this past week.

Thanks to our friends at What The Trend, we have yet another interesting stats-eye-view of the Twitterverse. Because this is a topical list, hashtag memes and games have been omitted from the chart below.

Beyond Justin Bieber, Follow Friday, and Music Monday — the reigning trend champs — St. Patrick’s Day made an appearance as people tweeted their revelry, and Lady Gaga crept up on the list with the premiere of her new video on Vevo and a tour in New Zealand.

The Jonas Brothers hung tight near the middle, while circle enthusiasts everywhere tweeted vigorously about Pi Day on March 14th, spurred on no doubt by the charming Google doodle that commemorated the occasion.

If you own a TV or computer, you probably know that March Madness is upon us, and bracket-related tweets have been flying around the web all week, landing the term at number seven.

Rounding out the chart are two more singers who made some news this week. Demi Lovato, the 17 year old actress/singer, stirred some buzz with her admission that she’s dating a Jonas Brother, and Chris Brown, the career-stunted R&B singer, reached out to his fans on the web for some help on making a comeback.

Strangely, tweets about the ongoing South By Southwest (SXSW) conference — one of the most talked about topics in tech and a favorite of the Twitter community — did not reach critical mass to make this week’s list. This is likely due to the lack of big announcements or product launches from the conference this year.
