Demi Lovato [1] isn't messing around this Halloween [2]! On Saturday, the 27-year-old star hit up a party dressed as the terrifying clown Pennywise from It [3]. Demi's look was scarily on point as she rocked a fluffy white dress with an orange wig and clown makeup. Even her mom, Dianna De La Garza, got in on the action, dressing as It character Georgie Denbrough. "My mom is the best," Demi captioned a snapshot of them together. Throughout the night, the "Sorry Not Sorry" singer [4] got down on the dance floor alongside stars such as former As the Bell Rings costar Seth Ginsberg and Paris Hilton [5].
Demi kicked off her Halloween [6] celebrations on Oct. 25 with a Marie Antoinette costume. Taking us back to 18th-century France, she struck a couple of fierce poses in a corseted minidress with a blond wig and pearls. "Halloween round 1... I told y'all I don't play on Halloween!! It's my time to shine," she wrote. "Glam team killed it." See photos of Demi's incredible costumes ahead, then check out more Halloween looks from other stars [7]!
