The very public feud between leading trainer Gai Waterhouse and powerful owner John Singleton is over with the pair reconciling at the Gold Coast, reports Racing Network.

Waterhouse and Singleton famously fell out following the All Aged Stakes in 2013, with their relationship seemingly in tatters as a result of the long-running inquiry in to the performance of star mare More Joyous.

But the two high-profile figures have mended their differences with Waterhouse buying a More Than Ready colt, out of Fashions Afield, from Singleton for $150,000 at the Magic Millions on Thursday.

“It was a lovers tiff. I was very sad when it happened and I am very pleased he apologised and we have moved on,” Waterhouse told News Limited.

Singleton and Waterhouse hugged after the purchase of the colt, a sign that the relationship is well and truly back on good terms.

“When you have loved someone since a little girl and there is a big blow up, well, you have just got to move on,” Singleton told News Limited.

“I remember when her father Tommy Smith sent her over to me to talk her out of acting and I have known her since then. We have had so much success together.

“I am such a wuss. Every time I saw her I just wanted to give her a hug. Really it was just a domestic tiff that played out across 23 front pages.

“If people ask me I am not going to talk about it. As far as we are concerned it just didn't happen. And if it did — it was all my fault.”
