The couple’s Beverly Hills date night comes on the heels of the billionaire and businesswoman’s move to Miami, which Bezos announced in November.

Last month, the couple was spotted settling into the Florida city, walking arm-in-arm on a daytime date at the Coconut Grove Arts Festival.

In January, Sánchez dedicated a sweet Instagram post to Bezos on his birthday.

Alongside a collection of photos that included a picture of the businessman as a child and one of the couple together, she wrote, “Today is another day where your laughter fills our home, and that smile of yours lights up every room.”

“Wishing you an abundance of simple joys and quiet moments of happiness,” Sánchez continued. “May this year be filled with everything you love, from peaceful mornings to joyous celebrations. I hope each day brings you countless reasons to smile, just like you give me a reason to smile every single day. Love you, and happy birthday, my love.”
