The rapper, 46, and his wife had recently been seen without their marriage bands on, amid rumours her new album Lemonade made reference to his alleged affairs, reported Daily Mirror.
However, he has now posed for a picture and the ring can clearly be seen on his finger in a move that could silence speculation about the strength of their relationship.
The photograph comes after an adorable video showed Jay Z dancing with the couple's four-year-old daughter Blue Ivy at a recent show of Beyonce.
