Paris Hilton transforms into her friend Britney Spears during her pop heyday while duplicating her iconic Child One Extra Time look in Halloween snaps.

Paris Hilton took inspiration from one of her old friends this Halloween, as she replicated one of Britney Spears' most iconic looks for the spooky occasion.

Posing for a jaw-dropping photo shoot, the heiress dressed in an outfit reminiscent of Britney's famous schoolgirl outfit from her 1999 hit… Child One Extra Time.

Paris showed off her incredible figure in a daring white cropped shirt and gray schoolgirl skirt, as she posed in an idyllic '90s version of a high school hallway.

With a book in hand and her hair in cute pigtails, the star mimicked the non-melting butter look from the innovador video, which made Britney an overnight sensation.

Posting the snaps to her Instagram, she captioned the post: 'It's Britney bitch. I love you icon.'

Britney and Paris have enjoyed a two-decade long friendship, supporting each other through various ups and downs.

They were often seen in the mid-2000s enjoying nights on the town in Los Angeles, sometimes accompanied by Lindsay Lohan.

In August, Paris revealed that Britney stopped by her house “a couple of weeks ago” because she “loves visiting the babies, especially little Phoenix,” on Talk Store Live.

'So it's so nice to see her with the babies. “She loves kids so much,” he added, adorably sharing that Britney danced with Phoenix on Paris' upcoming sophomore studio album, Infinite Icon.

Last December, Paris warmly wished Britney a happy 42nd birthday and shared a series of photos of the couple together in the 2000s.

In her caption, she noted that she and her friend have had “so many fun memories together.”

“I love you so much,” she gushed as she addressed the Poisonous hitmaker directly. 'Sending you lots of love on your special day! Keep shining sister.'

To celebrate her birthday, Britney spent the day with her mother, Lynne, as the pair now appear to be on good terms after years of being estranged following their 13-year conservatorship.

Britney and Paris have had a long history of friendship dating back to her partying days with Lohan in the mid-2000s.

Paris has consistently supported Britney over the years and has been a frequent presence in her friends' Instagram comments.

The singer even gushed about the Easy Life star, saying she was one of the “kindest” people she's ever met in her memoir, The Lady in Me.

During an appearance on Kelly Clarkson's talk show in late November, Paris recalled “crying” when she read the things Spears wrote about her.

Kelly noted that Britney had written in her story that “one of the people who was kindest to me when I really needed kindness was Paris Hilton.”

Britney had also written that Paris “encouraged me to have fun for the first time in a long time.”

Last Halloween, Paris paid a special tribute to Britney by dressing up as the pop star in the iconic blue ensemble from her Poisonous music video.

In response, Paris, who also published a memoir earlier this year, said it “meant a lot” to her.

“I was crying when I read that,” she said. “That really touched me.”

She continued to gush about her friend: 'She's so strong. I love her so much and I'm so proud of her for speaking her truth and writing this whole book.

“That quote meant a lot to me when I read it,” he added.

Paris even channeled Britney and dressed as her for Halloween last October.

For one of her costumes, she wore the same outfit that Britney wore in her iconic Poisonous music video.
