哈利波特中吉德羅·洛哈特的原型是誰？

會不會是貝克漢姆？

能看出洛哈特的形象基於真人，題主的洞察力也是很讓人佩服的。到目前為止，羅琳親口承認的參照了現實人物的角色就只有洛哈特一個。以下是2004年8月愛丁堡圖書節上羅琳的訪談節錄：

Are any of your characters based on real people?
請問書中有沒有基於真人創作的角色呢？

The only character who is deliberately based on a real person is Gilderoy Lockhart. [Laughter]. Maybe he is not the one that you would think of, but I have to say that the living model was worse. [Laughter]. He was a shocker! The lies that he told about adventures that he』d had, things he』d done and impressive acts that he had committed… He was a shocking man. I can say this quite freely because he will never in a million years dream that he is Gilderoy Lockhart. I am always frightened that he is going to turn up one day. He is just one of those people from your past whom you feel you have never quite shaken off. I will look up one day at a signing and he will say, 「Hello, Jo」. [Laughter]. Other people have contributed the odd characteristic, such as a nose, to a character, but the only character who I sat down and thought that I would base on someone is Gilderoy Lockhart. It made up for having to endure him for two solid years.
洛哈特是唯一一個我有意參照了現實人物的角色（笑）。可能出乎你的意料，但是我不得不說，他的現實原型還要更差勁（笑）。他真是語不驚人死不休！他的那些冒險和偉大事迹全都是胡說八道……他真的很愛嘩眾取寵。我可以毫不顧忌地把這些說出來，反正他做夢都想不到自己就是洛哈特。其實我總是害怕有一天他再度出現。他就是那種你只是過去認識而已，卻總是陰魂不散的人。也許將來我在簽售會上抬起頭來，然後他就在那「你好呀，喬」（笑）。有些角色帶了現實人物身上的某些奇怪的特徵，比如鼻子，但是洛哈特是唯一一個我下定決心要完全基於真人來寫的角色。我可是忍受了這個人整整兩年。

總之羅琳到頭來也沒有告訴書迷真·洛哈特是誰。可以確定不是羅琳的前夫，洛哈特只不過是愛吹逼而已，根據羅琳的描述，她的前夫是個無恥的惡棍。形象差太多了。羅琳應該是在官網上明確否認過，具體怎麼說的我還得找找。

2004年愛丁堡圖書節訪談全文（英文）

一個相貌英俊，第一面總會打動年輕女性的芳心，但相處久了就覺得此人噁心，甚至不想再見面……

妥妥的羅琳的前夫嘛！
