She’s back! Sia took the stage on ‘Jimmy Kimmel Live’ March 14 to perform her hit ‘Bird Set Free,’ and as usual, it was beyond amazing. Watch the Performance here!

She may be covering up her Face (as usual), but there’s no denying that Sia’s voice is Totally incredible. The singer proved that once again during an appearance on Jimmy Kimmel Live! March 14, during which she sang her song “Bird Set Free” and put on an artsy performance. Check it out here!

Sia wore a platinum blonde wig for the performance with the long bangs totally covering her face, and her massive, black and white, polka-dotted bow is totally insane. Just like we’re used to seeing when she takes the stage, Sia kept her concentration totally on the vocals, standing still at the microphone while the focus was on an incredible dancer to her side.

The 40-year-old has consistently expressed a desire to remain a somewhat private figure, hence the decision to keep her face covered while in public. However, she’s not always hiding — after the red carpets and press appearances are over, even Sia likes to let loose a little. Case in point: When she took the wig off at a pre-Grammys party last month.

The March 14 episode was a big one for Jimmy Kimmel…not only did he have Sia performing, but he had Bachelor Ben Higgins and his fiance, Lauren Bushnell, on for their first talk-show appearance since the reveal of their engagement. The lovebirds played the newlywed game and jokingly revealed what annoys them about one another, and it was completely obvious that they’re SO happy together. Maybe Sia will perform at the wedding?!

What did you think of Sia’s performance,? Do you think she’ll EVER perform without a wig?
