How Britney Spears responded after Hailey Bieber dressed up as her for Halloween

Hailey Bieber dressed up as Britney Spears for Halloween - and the singer loved it.

Bieber, a model and wife of Justin Bieber, posed in four of Britney’s most iconic looks to celebrate Halloween.

In pigtails and a school uniform, the 24-year-old looked like a double for Spears in the 1998 “Baby One More Time” music video.

She also wore the red jumpsuit from “Oops I Did It Again” and the skimpy pink ensemble from the “Slave 4 U” music video.

Posing on a bed holding a Tinky Winky plushie, she channelled Spears’s jaw-dropping Rolling Stone cover from 1999.

Posting on Instagram, 39-year-old Spears shared a picture of lipstick to her Instagram, with a caption outlining how she celebrated the end of her conservatorship.

Spears referenced a green shirt with shoulder pads she donned in four previous posts and said the only person she has seen wearing shoulder pads is Hailey Bieber.

“She was me for Halloween,” Spears wrote. “I think I won brownie points with my kids! But seriously though… how freaking cool is that?”

Spears has also been celebrating the end of her conservatorship over the weekend, and said she has been on “cloud nine” since the court-ordered arrangement officially ended on Friday.

She wrote: “I actually got my first glass of champagne at the most beautiful restaurant I’ve ever seen last night! I’m celebrating my freedom and my birthday for the next two months! I mean after 13 years I think I’ve waited long ENOUGH!

“I’m so happy my lawyer Matthew Rosengart came into my life when he did… he has truly turned my life around… I’m forever thankful for that!

“What a sight seeing so many people celebrating my victory… I love my fans so much… so thank you!”

Following her legal victory and her new engagement to Sam Asghari, things are definitely looking up for the star.
