Dr. Oz and Lisa's longtime romance had a unique beginning, which they've both spoken openly about in the past.
Their parents set them up and they were even present on their first date. However, when Lisa arrived at the restaurant, she didn't realize who her future husband was and mistook him for a staff member. "I thought he was the maître d," she told Yahoo Lifestyle. "I was like, 'Wow, that waiter is so hot.'"
Mehmet acknowledged that their relationship was "sort of an arranged marriage".
That first date wasn't a success though, and Lisa quipped: "He didn’t speak to me the entire dinner. He spoke to my mom."Even so, he called her up the next day to ask her out again.
"He said, ‘Do you want to go out next weekend?’" Lisa added. "And I said, ‘Only if you don’t have any other dates because I’m only dating you if you’re not dating anyone else.'"
Like any couple, they have had their ups and downs and it was an argument which sparked his decision to ask her to marry him.
The lovebirds were embroiled in a row seven months into their romance and he told Yahoo Lifestyle that when she stormed off he realized he wanted to spend the rest of his life with her.
"I chased her down the street, picked up a tab from an aluminium can that was on the ground, and presented it to her," he said of his spare-of-the-moment proposal.
Mehmet and Lisa tied the knot in 1985 and have never looked back. Not that marriage isn't hard work. Lisa told Shape magazine: "We fight a lot and there are times when we're bored with each other," but they always work out their differences.
