It's already time for Fashion Week again? How did that happen? And not just Fashion Week, but the one that includes New York's annual Fashion's Night Out event. This evening marks the third-most important night of the year for Anna Wintour (besides the Met gala and whenever the president is in town), and we're looking forward to all the celebrity sightings that are sure to occur. Here are our five best guesses of A-list names to appear tonight.

1. Ryan Lochte: The Olympic swimmer was already spotted last night at the Joseph Abboud menswear show at the New York Public Library ... marking the first and last time you will ever see "Ryan Lochte" and "public library" in the same sentence. We just hope he'll be able to pick up some styling tips and avoid future disasters like this one. (We should have known Mr. Lochte would show up at any event that promised a sighting of Kanye West.)

2. Katie Holmes: The recent hermit is making her first appearances at New York's Fashion Week. Her Holmes + Yang fashion collaboration with stylist Jeanne Yang is getting its first Lincoln Center runway show. In the meantime, she's already shown up at the Style Awards, held last night in the same location, presenting the "Designer of the Year" award to Caroline Herrera, so there's a good chance she'll be sitting front-row at her show. Not to mention that she's just been announced as the face of Bobbi Brown Cosmetics. Looks like life's good after Tom.

3. Sarah Jessica Parker: Now that she's such good friends with Anna Wintour and Oscar de la Renta, how could the star prepare for an upcoming Glee cameo anywhere else?

4. Kim Kardashian: She'll be taking a break from talking about the economy on CNBC to tackle fashion at Lord & Taylor tonight. (She'll be there selling her new perfume, True Reflection.)

5. Pippa Middleton: O.K., it's a long shot, but there's a possibility that Kate's sister will stick around post-birthday/U.S. Open and see all the beautiful people at Fashion Week. Especially since she's having so much fun juggling the men here.
