Last night, Lorraine, who celebrated her 60th birthday earlier this year, took to Instagram to share a picture of the pair during their meal out, which was a gift from their only daughter Rosie.
The 25-year-old treated them to dinner at the restaurant in Marlow.
Lorraine and Steve could be seen holding up their deserts, which had a little personalised chocolate label with the words Happy Anniversary written on it.
The mum-of-one captioned the picture, which she shared with her 378,000 followers: “A lovely lunch as a present from @rosiekellysmith at #theivymarlowgarden to celebrate our anniversary. Just perfect.”
Earlier in the day, Lorraine posted a throwback picture from their nuptials on the picture-sharing site and paid tribute to her husband of almost 30 years.
She captioned her post: “So this happened 28 years ago!”
“Happy anniversary to my husband Steve who makes me laugh and is always in my corner. #anniversary #love #happy.”
Their daughter Rosie also posted an old picture of the couple online to mark the special occasion.
She captioned the snap: “My faves, Happy Anniversary.”
Lorraine reposted the photo and jokingly added: “We were five years old.”
