Sia Marries Filmmaker Erik Anders Lang in Private Palm Springs Wedding

Singer surprises fans with wedding news just two months after announcing engagement.

This couple is just all about surprises!

Two months after making their engagement public at a New York City gala, multiple reports say Sia and documentary filmmaker Erik Anders Lang are now happily married.

The couple said "I Do" Saturday night in a private wedding held at Sia's home in Palm Springs, Calif.

"Omg omg I'm so excited," Sia tweeted to her followers earlier in the day. We should have known something big was coming!

The vocal singer has been keeping her relationship with Lang very quiet in the past several months.

In fact, it was actually Lang who revealed the couple's engagement news back in June. "That's an engagement ring folks," the filmmaker revealed on Instagram as the twosome posed on the red carpet.

Many music fans will recognize Sia as the voice behind David Guetta's smash-hit, "Titanium," as well as Flo Rida's, "Wild Ones."

The talented singer also deserves plenty of credit for writing and producing hits for Katy Perry, Beyoncé and Britney Spears.
