After promoting her new line of hair extensions earlier Thursday , Paris Hilton and boyfriend Benji Madden stopped by The Late Show with David Letterman in New York City.

Paris gushed to David about her “best friend” Benji Madden (”It’s forever… he’s changed my life”), gushed about “definitely” having a baby and a family like her other best friend Nicole Richie, and gushed about her new range of Prosecco, saying that Champagne in a can is “sexy” (Dave: “A Bud in a paper bag is sexy, too”).
