Jay-Z and Beyoncé Knowles wrapped up their French vacation with Blue on Saturday. The trio was in St. Barts to celebrate Beyoncé's 31st birthday and hung out on a yacht off the coast. Jay-Z and Beyoncé headed into town to enjoy a special birthday dinner last week and also popped up on shore on another leisurely afternoon. Blue cuddled with her parents during the lavish getaway, which ended just in time for Jay-Z to get to London and perform at the Paralympics closing ceremonies on Sunday. Beyoncé will be back in the spotlight tomorrow since she'll appear on the season premiere of Anderson Live in a prerecorded interview. Beyoncé talked about changing diapers and even added that Jay-Z is "actually very good" at it, too.
