‘So much I learnt from you. So much I am still learning. Today, you’re far away but I’m wishing you a Happy birthday and a beautiful day,’ he added.

Simone and Jono cosied up on the balcony at the eatery, with the blonde beauty taking selfies while the couple passionately kissed.

They struggled to keep their hands off each other, cuddling close together and chatting, each smiling fondly at the other.

Jono shot a smitten look at Simone as she took a photo of the two of them, before they nestled in together to share another smooch.

Romance rumours between the trainer and the catwalk star emerged last week.

Talk that the glamorous pair may be an item was stirred when they were spotted at a US National Basketball Association event sponsored by Hennessy, the French cognac, reports The Daily Telegraph.

Meanwhile a source, identified as a ‘friend’, told the Daily Telegraph that Jono and Simone were spending a lot of time together.

‘They enjoy each other’s company a lot,’ the anonymous friend could confirm.

The report said that the Australia’s Next Top Model star first met Jono a few years ago.

Jono and Amy split early last year, but decided to keep up appearances before making an announcement.

While they are no longer together, they remain friends and continue to operate their fitness empire together.

The estranged couple first met on MySpace 13 years ago, before later running into one another at a nightclub and falling in love.
