Beyoncé and Jay Z cracked up while watching the Brooklyn Nets game on Monday, letting loose during game four of the NBA Playoffs match against the Miami Heat in NYC. The pair's sporty date night came after the release of video footage showing Beyoncé's sister, Solange Knowles, attacking Jay Z in an elevator last week following a Met Gala afterparty. In the video, Solange can be seen punching and kicking her brother-in-law before she's restrained by a bodyguard. It isn't clear what caused the buzzed-about incident, but if Beyoncé and Jay Z's smiley date night is any indication, it looks like they aren't too fazed by the headlines. Take a look at the couple's sweet courtside interaction below.
