Eva Longoria: Have you spotted the 'sexpot'?

Wine-lover and Hollywood star Eva Longoria has spent the day at Waiheke Island vineyards.

The former Desperate Housewives star posted a photo on social media of her standing in the vines at Destiny Bay Vineyard.

Earlier, she'd woken up with a hangover because of "too much New Zealand wine last night!" at Michael Dearth's The Grove restaurant in central Auckland.

She admitted to the Herald in an interview yesterday: ""I'm a big wino, so I'll definitely be visiting some wineries."

Yesterday, she teased fans with a picture of her wearing a helmet and harness saying "guess what we did today!" indicating she had bungee jumped. But then admitted she hadn't.

The pint-sized star is here to judge the Specsavers Spectacle Wearer of the Year competition - is accompanied by her Mexican businessman boyfriend Jose Baston.

The star said she may be paying for a few meals while she's here - all in the name of good karma.

Earlier this week in Sydney, an anonymous diner paid her bill. "They didn't even tell me, didn't even present themselves to me, didn't even want a picture or anything. They just paid it and left and I felt like I really wanted to say thank you."

The gregarious star said she's likely to pay it forward in Auckland.

"I do it all the time. I take care of a lot of people's bills all the time without telling them. I'll usually leave the restaurant and say 'Make sure to pay that person's bill'. It's about paying it forward.

"We do so many good things for people that when something like that happens for us, we're surprised, but I think it's karmic."

A role in The Young and the Restless secured the beauty queen's big break as model-turned-trophy wife Gabrielle Solis in Desperate Housewives in 2004.

Since then, she's won multiple Sexiest Woman of the Year Awards, including Maxim's Woman of the Year 2014.

She turned 40 in March and said there are no secrets to her sexpot status; it's all "hard work". "I diet and I exercise all the time ... I feel like I've been on a diet since 1993."
