Beyoncé opted to keep her 31st birthday celebration low-key.
Instead of throwing a star-studded party, attended by all her famous friends, Beyoncé decided to spend the special day with her gorgeous 7-months-old daughter Blue Ivy, and husband Jay-Z as the family enjoyed a Mediterranean cruise.
Jay-Z, 42, appeared to have gone all out to make his wife's birthday as special as possible, decorating their boat with balloons and streamers in celebration.
Birthday girl Beyoncé was spotted clutching a large glass of white wine as she marked her 31st, looking chic in a blue and white cricket-style jumper and a pair of matching shorts.
She and Jay-Z were seen enjoying an evening drink on the deck of the boat, with the pair looking as in love as ever as they made the most of each others' company.
