Kelly Clarkson Gets in Christmas Spirit on Halloween With Awesome 'Elf' Costume

By
Christmas came early in Kelly Clarkson's house!
On Halloween, the American Idol alum dressed up as Will Ferrell's hilarious character in the 2003 holiday comedy, Elf. As for her husband, Brandon Blackstock, he successfully channeled Chris Hemsworth's character in Snow White and the Huntsman.
"Happy Halloween from the Huntsmen and Buddy the Elf #santascoming #iknowhim #embarrassingcostumesrthegreatest #mymomcantbelieveimpostingthis," Clarkson tweeted on Monday night.
This is the mother of two's second Halloween costume. On Friday night, Clarkson dressed up as Sia and performed "Chandelier" on Facebook Live. "Welcome! Hey, what's up? I'm Sia this Halloween. What?!" she announced. "She's one of my favorites, so I thought I'd wear a wig and be Sia. I'm gonna cover a Sia song right here real quick, and I'm gonna talk to you."
"Anyway, this is called 'Chandelier,' so here we go," the 34-year-old singer added. "Here you go, Sia. I hope you like it."
Clarkson wasn't the only star to dress up as a pop star. Kylie Jenner also nailed her "Dirrty" costume, and got Christina Aguilera's approval. Check it out:
