The Fug Girls suggested that Mary-Kate Olsen was flashing a giant grin at Rock & Republic because she's, ahem, "getting laid." Our spy saw MK's versatile smile, too. While waiting backstage with Jessica Szohr, a waiter bumped into Mary-Kate and spilled an entire glass of champagne down the front of her outfit. "She was so sweet about it," said the spy. "The waiter couldn't stop apologizing, and she was just like, 'Seriously, it's okay. I'm wearing black.'" The spy did say that after the ten thousandth apology, she gave the waiter her "Go. Away. Now. Please." grin. But it was a grin, nonetheless!
