The "Fabulist" host teased her Insta followers on Oct. 2, 2014, with a shot of the 10 inches of hair she'd cut and tied together in a ponytail before debuting her look with a selfie a few hours later.

"Short hair don't care," she wrote of the cut that was crafted by hairstylist Chris McMillan, who maintains Jennifer Aniston's locks and Miley Cyrus' pixie 'do. Colorist Justin Anderson, who has worked with Kelly Osbourne and Emma Roberts, spiced up her blond mane.

Kristin was inspired to cut her hair by Britney Spears, who recently debuted a bob. "We're wildly obsessed with Britney Spears, so she sent me pictures back and forth of her new cut," Justin told People of how he and Kristin mapped out her new look.

How does Kristin like her new look? "She's loving it!" Anderson added to People. We can certainly tell. She was photographed strolling through Beverly Hills post-cut and didn't hesitate to run her fingers through her hair while flashing a big smile.
