{blackbabes} PDA of the Day: Beyoncé and Jay-Z Kiss Aboard Luxurious Yacht in Mediterranean Sea

If the boat's a-rockin', don't come a-knockin'!

Hope Jay-Z and Beyoncé's crew knows that. The power couple looked very much in love Thursday, sharing a sweet kiss aboard their private yacht as they continue their vacation in the south of France.

Bey, who celebrated her 31st birthday Tuesday, looked chic and laid-back in a colorful caftan and sunglasses. Hov rocked a nautical look, wearing neon-green board shorts and a white T-shirt.

Blue Ivy is also getting a taste of the Mediterranean with her superstar mom and dad. Just 8 months old and already living the good life!
