And during a recent vacation to Las Vegas

to celebrate their 13th wedding anniversary,

Beyoncé and Jay-Z showed

that they were still as happy as ever.

The 39-year-old singer of Black Is King gave her fans an inside peek at the couple’s romantic retreat on Saturday by posting a number of pictures to her website and Instagram account.

Taking their own approach: On Saturday, Beyonce posted a number of pictures to her Instagram account from her and Jay-Z’s anniversary trip to Las Vegas.

The Crazy In Love singer captioned the pictures, “Sin City,” indicating that the theme of the photo set was being naughty.

Large diamond hoops, a choker, gaudy sunglasses, and glossy buttons added a lot of glitz to the ensemble.

Her mirrored box purse and pointed red velvet heels with ankle bows knotted together completed the ensemble.

The 51-year-old spouse of Beyoncé wore a long-sleeve shirt honoring the late artist Noah Davis’s The Underground Museum in Los Angeles, keeping things casual.
