Asked by the presenter what the employee said to her next, she responded: "She said: 'Yeah. 'I made a dress I want to send it to you, I work at the Apple Store here in San Antonio'.
"And I'm like, what? Did someone give out my email? Or my phone!
"'I saw your phone number from your profile, I just wanted to call and say, 'Hi, I'm a fan.' There are a lot of privacy issues."
Apple is yet to respond to a request for comment on Longoria's allegations.
Her comments come as more than 100 household names have been the target of online thieves, who have stolen scores of naked photographs and intimate videos and posted them on the website 4Chan.
Several of the images - in particular, two of Hunger Games star Jennifer Lawrence - quickly circulated on Twitter.
Among others the list includes Ariana Grande, Jessica Brown Findlay, Mary E Winstead, Rihanna, Kim Kardashian, Mary Kate Olsen, Mary E Winstead, Cara Delevingne, Kate Bosworth, Selena Gomez, Vanessa Hudgens, Kate Upton, Kirsten Dunst and Kaley Cuoco.
The FBI and Apple are both conducting investigations into the apparent widespread invasion of personal accounts thought to be connected to the iCloud service.
A spokesperson for Jennifer Lawrence, the most high-profile actress to be hacked, said: "This is a flagrant violation of privacy. The authorities have been contacted and will prosecute anyone who posts the stolen photos of Jennifer Lawrence."
Justice and Grande have both said that the pictures are fake, although Lawrence's spokesperson verified the authenticity of the pictures of her.
Meanwhile, representatives for Upton said they were "looking into" the authenticity of the indecent images.
Ricky Gervais went on a back tracking spree on the social media site after he was criticised for 'victim blaming', while Emma Watson took to Twitter to condemn the breach.
The anonymous hacker recently admitted that they were unhappy with how much money he or she has made from circulating the stolen photographs via 4Chan.
