The singer, who secretly dated drummer Jon Moss during the band's peak, said the pair now have a "healthier" relationship, after Moss married a woman and went on to have children.
"Oh no. We're really good mates," he told The Sun. "Jon has got kids now - beautiful kids and we're definitely over each other.
"I love Jon dearly and it's a much healthier kind of love now. He'll always be a really important part of my life."
The band will reform next year for a UK tour to celebrate their 30th anniversary, while Mark Ronson will helm their comeback LP.
