Halliwell, 40, said she misread the signs given by Michael but after discovering about his sexuality they became close friends, reported Sun online. "I'm totally off. My gaydar is useless well it's better these days.
With George Michael years ago I'd made plans to marry him, I used to practise kissing with his poster. Then we met and I started being all flirty eyes, licking my lips and the sexy poses and I just felt there was nothing coming back.
"Then I was chatting on the phone to him and he starts talking about his boyfriend and I'm like what? How could I be so wrong !" Halliwell said. After the misunderstanding, the pair became close friends and have helped each other through tough times.
"You know he's the only celebrity friend I have, aside from the Spice Girls, that I tell all my secrets to. I have long chats with him, he's like a brother. In the past I've played my music to him. He's very normal when you talk one-on-one with him." she added.
