THE principal at a leading English private school has resigned after she hired school facilities to a rapper who filmed an X-rated film clip on the campus.

Governors at Mill Hill School, where boarding fees cost up to £33,717 ($60,000) a year, have launched an investigation after rapper Stefflon Don's latest song "Pretty Girl" was filmed on the school premises.

The clip shows her smoking marijuana in a dormitory and dancing naked in a shower.

The track, which features south London singer Tiggs da Author, has already been viewed more than 500,000 on YouTube and 350,000 on her Instagram account.

In the video Stefflon Don, real name Stephanie Allen, wins over her new classmates after playing in a football match where she swears at an opponent for diving.

She says to the girl: "What the f*** you're just gonna drop like that?"

She is later seen dancing naked in the showers of the changing rooms and smoking marijuana in a boarding dorm.

Other scenes show people smoking cigarettes outside the grand pillared entrance to the school that counts Richard Dimbleby and Sir Denis Thatcher among its alumni.

Chris McGovern, chairman of the Campaign for Real Education, told the Daily Mail: "The message being sent by this video popularises everything which good schools should be against - drug-taking, swearing, and overt sexuality.

"These are all things which schools should be trying to guide pupils away from, not promoting them. Parents who are paying the fees for their children to go there will be appalled."

The school's website includes a list of facilities it is possible to book - such as sports pitches, classrooms and the school chapel.

It adds: "All events will be managed and can be catered by our highly skilled staff."

The school announced yesterday its first female head teacher Frances King has stepped down from her role, but denied it was related to the filming of the video.

A spokesman said governors grant permission, "from time to time", for location shooting "to raise funds in accordance with their charitable objectives."

He added: "Strict controls are in place on the suitability of the content. The governors are investigating how this filming was allowed to proceed and apologise for any offence caused."
