". . . What should we do for our wedding anniversary on 11/11 this year??,” Hilton also asked her Instagram followers

Paris Hilton has found long-lasting love with Carter Reum.

The socialite and "Stars Are Blind" singer, 42, celebrated the latest milestone in her relationship with her husband with a sweet tribute post showing the pair throughout their time as a couple, looking every bit as happy as their wedding day.

Hilton started her Instagram post with a cozy shot of the two laying down in a hammock with Reum’s arms around her as they both smiled. A second photo showed the pair relaxing after a swim with Hilton in a pink water suit sitting in Reum’s lap with her arms around him as he beamed at the camera.

She also shared a snap of the two getting ready for a night out, all glammed up with him in a suit and tie and her in a gown, as they smiled at each other.

Hilton also gave fans a glimpse at some more casual moments too, like the couple cozying up on a sofa in their home with Hilton’s teacup puppy and a shot of Hilton smiling up at her husband on the beach.

"This week was our 45th month anniversary 💗 what should we do for our wedding anniversary on 11/11 this year??,” Hilton asked her followers on Instagram of their nearly four years together, while also hashtagging the word “Love.”

In response, Reum, 42, shared his own sentimental words about what the entrepreneur means to him.

“I’m the luckiest guy in the world to be your teammate and best friend ❤️❤️ the sparkle you bring my life is unmatched ✨,” he commented on the post.

Hilton is no stranger to sharing her love on social media. Last month, she celebrated her husband with a video of the pair sharing some romantic moments together set to the tune of Bebe Rexha and David Guetta's track "One in a Million.”
