Lady Gaga this week becomes the only act in the digital era to top the 5 million sales mark with both of his, her or its first two hits. She accomplishes the feat as her second single, "Poker Face," follows the lead of her debut hit, "Just Dance" (featuring Colby O'Donis). The long-established Black Eyed Peas are the only other act with two songs at or above 5 million.
But I think it will be #5 or #6 
Where the haters at now? 
Flop my ass!
