Love on the brain.

Before they welcome their first child, Rihanna and A$AP Rocky enjoyed a romantic Valentine’s Day aboard a yacht.

On Wednesday, the pregnant singer shared photos from their date night, including a floral bouquet made of Legos and a pink Lego rose in Lego wrapping paper.

They dined on caviar while taking in the ocean views and Rih received a greeting card featuring a photo of Method Man and Mary J. Blige alongside the lyrics to their collaboration “All I Need.”

Rihanna sported a pinky ring with her nickname “Rih” spelled out in diamonds, but it’s unclear if it was a gift from Rocky. The couple was also pictured taking in the sunset with Rih’s pregnant belly on display.

“nerdz,” Rihanna captioned the pics.

Last month, the singer and rapper, both 33, announced that they are expecting a baby together. They made their first red carpet appearance at Rihanna’s Fenty Beauty Universe event in Los Angeles on Friday night, where the fashion icon opened up about pregnancy.

“I’m enjoying not having to worry about covering up my tummy,” she told PEOPLE. “If I feel a little chubby, it’s like, whatever! It’s a baby!”
