Toasting love in style! Kyle Richards and her husband Mauricio Umansky spent the weekend on a holiday getaway to Puerto Rico to celebrate their 17th wedding anniversary, and the Real Housewives of Beverly Hills star had some interesting reading material on hand.

In a snapshot that Umansky shared on his Instagram account on Saturday, Feb. 2, Richards, 44, looks to be reading E.L. James' erotica novel Fifty Shades Darker.

"I like the book my wife is reading," the CEO/founder of real estate brokerage The Agency captioned the photo, which revealed an infinity pool and waves crashing in the distance. "I'm not sure I will ever move from this cabana."

The happy couple, who have three daughters together (Richards has a fourth daughter from a previous marriage), also couldn't resist taking a few photos of each other as they soaked in the rays at Dorado Beach.

In one, a red bikini-clad Richards lounges on a chair on the beach, reading her book. In another, a shirtless, buff Umansky shows off his impressive physique standing nearly knee-deep in the water.

"The ocean not bad either. Sorry no speedo this time," he joked to his Twitter followers.

The pair even managed to enjoy the Super Bowl on Sunday, Feb. 3 -- though they weren't packed into a crowded bar or even enjoying the game from a couch in Los Angeles.

"Watching the Super Bowl on the beach," Richards shared on Twitter, alongside a shot of a big-screen set up against a tropical sunset.
