I knew Lady Gaga was popular but I didnt know she had this many fans.

Lady GaGa becomes just the third artist in the 16-year history of the Mainstream Top 40 airplay chart to collect three No. 1 songs from a debut album. "LoveGame" (Interscope) rises 2-1, marking Lady GaGa's third No. 1, following "Just Dance" (two weeks) and "Poker Face" (five weeks). The three songs appear on her top five Billboard 200 album, "The Fame." The set has sold 1,162,000 copies to date, according to Nielsen SoundScan.
