This is one Grammys collaboration we definitely did NOT see coming: Sia and Kristen Wiig together onstage for 'Chandelier'!

Sia has released her single from the "Fifty Shades Of Grey" soundtrack. Is it as good as Ellie Goulding's?

This Top 20 list is according to Billboard.com. Not that they actually know what they're talking about or anything, but see if you agree.

Sia is not surprised that her controversial video for 'Elastic Heart' has elicited "pedophilia cries" -- but she is sorry.

Jim Carrey has a dance off with Kate McKinnon and Iggy Azalea to Sia's 'Chandelier' in last night's Halloween-themed 'Saturday Night Live' episode.

Things got a little bit awkward during Britney Spears' Las Vegas residency when she appeared to be lip synching to Sia during a recent performance.

Congrats, Sia! The singer tied the knot with her boyfriend, filmmaker Erik Anders Lang.

Jay-Z knows how to pick 'em! We're not just talking about in his personal life, either (though really, ladies don't get any finer than Beyonce). We're talking about the soundtrack picks for 'The Great Gatsby,' which Hov himself scored. The latest track to hit the web is a contribution from Aussie chanteuse and songwriter Sia, called 'Kill and Run.'

David Guetta is probably the world's foremost DJ right now. Calvin Harris is right there with him, but when you look at Guetta's roster of guest stars, he wins. And he's brought back Sia for this new track called "Shewolf". No, not the same shewolf as Shakira had recently...
