Beyoncé and Jay Z had a rare date night on Monday when they dropped by a Brooklyn Nets game in NYC. The superstar couple munched on popcorn while sitting in their courtside seats to watch the Nets face off against the Oklahoma City Thunder. Bey and Jay kept things low-key after they spent the weekend celebrating Halloween in the Big Apple. On Thursday, Beyoncé and Jay took Blue Ivy Carter to a costume bash, with Bey and Blue wearing Jackson family-inspired looks and Jay wearing a Michael Myers mask. However, on Friday, the couple took an arty approach to their All Hallows' Eve ensembles when they visited a private party on the spooky night. Bey dressed up as Mexican artist Frida Khalo, while Jay donned a wig to disguise himself into American artist Jean-Michel Basquiat. In other Bey news, the singer has confirmed reports that she will be releasing new music this month when she debuts a box set for Beyoncé, featuring remixes and two new tracks, "7/11" and "Ring Off."
