I remember watching an interview of D12 doing a chart countdown on some urban music show, and Eminem was announcing the chart position of Lady Marmalade by Christina Aguilera (on which Pink features), and after he read out Pink's name he was like "lol, who?", so I'm not sure how far back he knew her. It was also funny, because after he read of Christina's name he should "BIIIIIIITCH".
