Nike opened a new flagship store on Mercer Street and went balls out, closing the entire block for an over-the-top opening celebration featuring a marching band, street vendors and DJ Mark Ronson. Click here to check out the scene. Spike Lee and Roger Federer opened the store’s front doors together and both Maria Sharapova and Serena Williams attended as well.

More pics and other goodies after the jump…

Serena, for one had a grand old time. Here she is on her blog:

Anyways I had a fun conversation with Spike and I think he is fab! As u all know I love acting so I hope we can work together one day… That would be awesome!!! lso I talked to Roger Federer! He’s so awesome! We were talking about the gold medals that we won and each of our experiences. It was cool to know that he felt the same way I did about winning a gold medal. It is such an amazing experience playing for your country and being able to bring back gold. He’s fun and so awesome! Clearly my fav player….

Let the romance rumors begin! Perhaps Common and Mirka won’t be getting to know each other in the players’ boxes, after all.

Here’s Maria Sharapova, flying solo. Despite all the high-profile U.S. Open events she’s been taking part in, the Russian doesn’t seem to have her heart in tennis right now, at least according to the NYObserver:

Ms. Sharapova, who will be sitting out the U.S. Open due to an ongoing shoulder injury, stopped by briefly. Will she be cheering on her tennis peers from the stands?

“No, no, definitely not,” she said. “I’m just here to work with my brands and to do things that I already had planned to do for a couple of days, and then I’m going back.”

So really, you won’t be watching the tournament at all, Ms. Sharapova?

“No, I won’t. Unless I’m working out and it happens to be on TV, I might catch it, but I don’t plan to watch it. I have so many things going on in my life, and this is a good time for me to work on all of the projects I’m working on.”

Here’s a Marketing 101 tip for Ms. Global Brandapova: don’t slag your own product, dummy. Sheesh. Not that I don’t understand her fatigue – I too, am becoming jaded just reading about all these overblown fashion/tennis/corporate mega events going down in NYC pre-U.S. Open. Seriously, Roger, maybe you should be using your down time to train and focus instead of hanging out with Don King and a marching band?
