Beyoncé’s in Paris right now with Jay-Z.  She’s not on her way to the  royal wedding—this morning’s news swore she and Jay we’re headlining  Will and Kate’s after party. A source told the Daily Star that the prince, who’s also invited Kanye West to the actual ceremony,  was psyched to dance to “Crazy In Love” post-dinner. Unfortunately, it’s not true. (Though if you were a prince and could  pick anyone to perform at your wedding wouldn’t Jay and Beyoncé be at  the absolute top of your list?)  A rep for the pop star says she’ll be  in New York for a shoot this weekend instead of in London. Beyoncé is, however, leading the way for fall’s number one trend—polka  dots on polka dots. She may be the only one who can make this  Christmas-colored Marc Jacobs look appropriate for spring. She paired  it with a black croc bag, no makeup and casual hair up top—a perfect  balance.
