Justin Timberlake joined friends in the stands at the US Open in New York on Saturday. JT and company cheered on Roger Federer during his match against Novak Djokovic, though Roger lost while Novak advanced to the finals. Meanwhile, Justin's on-again girlfriend, Jessica Biel, was spotted arriving at the Windsor Arms Hotel in Toronto yesterday. Justin and Jessica may have been apart this weekend, but they've been spending time together recently. Justin and Jessica rode bikes in Canada in August, and they also apparently shared getaways to Massachusetts and Colorado this Summer. The couple have more than just their rekindled romance to celebrate since over the weekend Justin was also honored with a Creative Arts Emmy for hosting Saturday Night Live.
