Suzi Quatro almost embarked on a romance with Alice Cooper in the mid-1970s, but the rockers decided to call it quits after their first kiss rather than risk their friendship.

Quatro and Cooper only once succumbed to their mutual attraction and immediately vowed never to go there again.

She says, "We had one long kiss and then both pulled back, looked at each other and said, 'No!'

"There was always an attraction but it was better to be friends, even if he later told a friend it was the defining moment of his life."
