Beyoncé Knowles and Jay-Z made it date night at the Nets-Knicks game in NYC on Monday evening. The twosome were rooting for Jay's Nets, of course, but they were also checking out NBA sensation Jeremy Lin who has been sparking "Linsanity" around the world recently. Beyoncé rocked sky-high heels, a bight blazer, and a big smile for the date night. It's among Beyoncé and Jay-Z's first public outings since the arrival of Blue Ivy Carter in January. Beyoncé and Jay shared a few intimate Blue Ivy pictures on their websites earlier this month, and the famous little one was even the subject of a hilarious SNL sketch starring Justin Timberlake over the weekend. The duo are reportedly both working on new music of their own, while also enjoying life as new parents to their baby girl.
