Film director Spike Lee shows up in Serena’s Williams friends’ box at the U.S. Open for the first time during her win over Ana Ivanovic on Tuesday. Williams said that the two are close friends and hang out in Palm Beach, Florida together. The two have also hit together.

"He's good," she said. "He's crazy. He wants to win more than I do. He's like, Hit to me really hard. I'm like, I can't hit to you really hard. I'm going to break your racquet if I do. He's like, No, go your hardest. I'm like, Really? He's actually really good. He's like really, really intense. I'm a little intimidated. Calm down, calm down."
