For one of the worlds most beautiful and photographed women you would think a low key birthday celebration would be out of the question, but this is exactly what musical phenomenon Beyoncé Knowles opted for to celebrate her 31st birthday.

Beyoncé alongside doting husband Jay-Z and daughter Blue Ivy, spent the day aboard a luxury yacht in which her husband had decorated with balloons and streamers as they cruised through the Mediterranean Sea.

Beyoncé kept her look low key as she donned a blue and white cricket jumper and a pair of matching shorts.

Celebrity friend Gwyneth Paltrow sent the singing sensation a handwritten note wishing her a happy birthday while Beyoncé’s mother paid tribute to her daughter’s birthday by saying 'God blessed me with one of the greatest gifts in my life on Sept. 4, 1981. Happy birthday.'
