Judging from the photos they each posted to Instagram on Tuesday, the controversial couple spent the very first day of 2013 together. "Good morning! Still haven't slept lol #hello2013," Rihanna, 24, captioned a pic that showed her peeking out from a polka-dotted comforter. Brown, 23, wrote simply "Mornings" under an image he snapped of what looks to be the same comforter. Breezy and RiRi's New Year's date is only the latest sign that they're back together after they split in the wake of his 2009 assault on her. The two were even more brazen on Christmas Day when RiRi tweeted a photo of them posing in front of a car, with her smoking a cigarette and him without a shirt under his jacket, along with the message, "Thug Life #merryChristmas." Festive, right? And just in case you still didn't get the picture, later that day they were spotted sitting courtside at a Los Angeles Lakers' basketball game at L.A.'s Staples Center.
