Beyonce's birthday isn't just a one-day event.

The "I Was Here" singe celebrated her 31st birthday Tuesday on a yacht on the Mediterranean Sea in the South of France with husband Jay-Z and daughter Blue Ivy, 9 months. To keep the celebration going, the birthday girl was treated to a romantic dinner with her hubby in Antibes, Frances Wednesday.

The busy mom -- who is the new cover star of Us Weekly's style issue, on stands Friday -- wore bright red lipstick for the occasion and styled her long hair curly.
