Serena Williams showed love to the Miami Heat while sitting courtside at Game 4 of the NBA Finals. The tennis star sat next to fellow athlete Usain Bolt, and even snapped a picture for her Instagram followers with the caption, "#Athletes." 

Despite the star-studded crowd cheering them on, the Heat fell to the Spurs, 107-86. Heat coach Erik Spoelstra even commented on the Spurs' performance. "They just played great and I can honestly say I don't think any of us were expecting this kind of performance. They were great. You have to give them credit for that. We just couldn't get into a rhythm on either side of the ball, and it went from there."
