Singer Beyonce Knowles celebrated her 31st birthday on Tuesday(9/4/12) by cruising on a yacht in the Mediterranean Sea, South of France with her husband Jay-Z and daughter Blue Ivy. The birthday girl relaxed at sea while dad Jay-Z doted on baby Blue.
In several candid shots, proud papa Jay-Z can be seen playing around with his little girl on deck. The seven-month-old especially took interest in some blue and white balloons that were used to decorate the boat. Mom Beyonce was later seen holding her precious baby girl.
