All grown up! 'Harry Potter' star Scarlett Byrne poses naked in new Playboy issue

She's all grown up!

Scarlett Byrne may have shot to fame as Draco Malfoy's friend Pansy Parkinson in "Harry Potter," but she's ready to take on more racier roles.

The former child star, who is now 26, posed naked for Playboy magazine -- and she shared the cheeky snap on Instagram.

She captioned the sexy photo: "Nude is normal."

The British actress had her back turned away from the camera in the black and white snapshot in what appears to be a balcony. Scarlett showed off her perky bum while covering her mid-section with a silk sheet.

In the caption, she also mentions that she penned a short essay titled, "The Feminist Mystique." She went on to thank the magazine and Hugh Hefner's son Cooper, who is the company's Chief Creative Officer and her fiance!

Her sexy shoot will appear in the magazine's March/April issue, and marks its return to full nudity after almost exactly a year without it. Pamela Anderson was the covergirl of the publication's supposed last nude issue early last year.

"I'll be the first to admit that the way in which the magazine portrayed nudity was dated, but removing it entirely was a mistake. Nudity was never the problem because nudity isn't a problem. Today we're taking our identity back and reclaiming who we are," Cooper Hefner said in a statement.

Since her "Harry Potter" days Scarlett has added to her impressive acting resume. She's had reoccurring role sin TV hits "Vampire Diaries" and "Falling Skies."

She and Cooper got engaged in August 2015, but have yet to tie the knot. Before Hugh's son popped the question, he flew to her native London so he could ask for her father's hand in marriage -- how stinkin' cute!
