Oops, Britney did it again. Her new song "3" debuted atop of the Billboard 100 chart this week. It's her third number one song ever. (Hard to believe, right?) And! It's the first time in three years that a single has debuted at number one. 2012 is only three years away. This all must mean something, right?

We think it just means that everyone's all about the ménage these days.

Jason Mraz has made history this week--his song, "I'm Yours," is now the longest running song on the Billboard Top #100 singles chart in history. It's been going strong at 71 weeks (and counting).

Miley Cyrus made history this week.

The Hannah Montana star is the youngest singer ever to have three number one albums on The Billboard 200 Charts.

The 16-year-old’s latest album, the soundtrack for Hannah Montana: The Movie, hit #1 in its fourth week on the chart.

The record was previously held by 19-year-old Britney Spears.

Let’s hope this is the only way Miley follows in Britney’s footsteps.
