Glee star Lea Michele's (Rachel) fans keep showing love to the new songs off her forthcoming album, Louder. Lea released "What Is Love?" on January 28, and the tune has been tearing up the iTunes sales chart. Way to go, Lea!

"What Is Love?" is a heartfelt piano ballad and is the fourth song from Lea's album to be made available on iTunes thus far, following previous singles "Cannonball," "Battlefield," and "Louder." The full album will be released in its entirety on March 4.

If you picked up "What Is Love?" on iTunes this week, you weren't alone. The song got as high as number two on the U.S. iTunes chart, with Katy Perry's latest single "Dark Horse" being the lone single that "What Is Love?" was unable to surpass on the chart.

And that's just in the U.S. The song did even better on iTunes charts in other counties. It hit number one in eight different nations, including Israel, Brazil, Finland, and Egypt. Not too shabby!

Meanwhile, Lea keeps popping up everywhere. She's on the cover of the current issue of Teen Vogue, revealing in an interview that she and Cory Monteith (Finn) had "insane love" for each other.

Do you adore "What Is Love?" as much as we do?
