Kelly Clarkson owned this Halloween as the Grammy-winning singer dressed up as another Grammy-nominated singer, Sia.

She went one step further and belted out one of her songs too.

In the Facebook Live video, Clarkson belted out of a cover of 'Chandelier' as she donned a white wig and channelled Sia for a phenomenal performance – which we all know is one of Clarkson's specialties.

"It's hard to—I don't know how she does this cause, you know, you can't see," said Clarkson after singing Chandelier.

"But it's also kind of awesome cause you're on your own little world when you're performing. I love that song. Everybody loves that song.

'Chandelier' was a huge hit for Sia when it was released in 2014, and its music video – which featured dancer Maddie Ziegler – became one of the most viewed YouTube videos posted ever.

However, Clarkson wasn't the only singer showing off her Halloween costume.

The 'Ain't My Fault' singer Zara Larsson performed her 30-minute set at Vevo's Halloween party in Liverpool last night (October 29) as Maleficent.

Back in July, Larsson opened up for Beyoncé at her Formation World Tour date at London's Wembley Stadium.

Meanwhile, singer-actress Bette Midler brought up back to our childhood as she dressed up as her iconic Hocus Pocus role—the child-eating witch Winnie Sanderson.

Hilary Duff and her boyfriend, however, have offended people after their Halloween costumes are deemed racist. She dressed up as a "sexy pilgrim" while her boyfriend, Jason, was a Native American.
