Dressed in her signature cooky attire, pop singer Lady Gaga hosted an album signing for her new album “The Fame Monster” Monday (Nov 23) at a Los Angeles Best Buy. Her good friend rapper Dr. Dre was also on hand and the two posed for pics for the press.

The “Bad Romance” singer reportedly spent over $1,000 on Papa John’s pizza for her “little monsters” (fans) who were waiting to meet her outside.

“Sending all my little monsters little pizzas for waiting all night for me at best buy,” she Twittered. “I hope you’re hungry … eat up I love u!” She also thanked her fans for helping make The Fame Monster a hit on iTunes. “To all my beautiful fans, I love you more than anything,” she Twittered. “Thank u 4 making the fame monster number 1 on itunes. You are the only reward I need x gaga (sic).”
