More than three decades after he tied the knot with Sheryl Berkoff, Rob Lowe is still madly in love.
To celebrate their 31st wedding anniversary, Lowe, 58, gushed over Berkoff, 61, in the caption of a sweet Instagram post which included a stunning black-and-white shot of Berkoff on the beach.
“Happy 31st Anniversary, baby,” he wrote on Friday. “Your love has made my world. You are as beautiful, knowledgeable, fascinating, kind, and hilarious as you were so many glorious years ago.”
“Partners in love for life!!” he added.
Lowe and Berkoff first met when the two worked together on the actor’s 1990 erotic thriller, Bad Influence. The couple rang the wedding bells in 1991 and now share two sons, Matthew Edward Lowe, 29, and John Owen Lowe, 27.
The post wasn’t Lowe’s only public love letter to Berkoff this summer: in June, he penned another tribute to her in honor of her 61st birthday.
“Happy Birthday to the love of my life,” he wrote at the time. “You are the whole package, and I am blessed. Here’s to many more years of love and fun! Xoxo.”
Earlier this year, Lowe opened up to PEOPLE about the moment he knew Berkoff was The One.
“I had the feeling that if I was ever going to be able to make it work with anybody, it was Sheryl,” Lowe said, adding that with her, he felt “seen” for the first time in his life.
“She saw things in me that nobody had ever seen before,” he continued. ” … I still think she’s the hottest, sexiest, most beautiful, insane, complicated, entertaining person that I know, in addition to being a great mother.”
