The couple were surrounded by a handful of other players, including Ian Botham, but that didn't stop them from kissing passionately in the middle of the sporting crowd in Scotland, reported Daily Mail.
Hurley was seen putting her arms around Warne, before planting several kisses on his lips. She also gazed at him lovingly.
The engaged duo even colour-coordinated their outfits. They stepped out wearing pink sweaters under their attire.
The pink touch to their outfits was likely to be a nod to the Breast Cancer Awareness month, a cause promoted by Hurley, 47, with beauty company Estee Lauder, of which she is an ambassador.
