Nicole Richie is stepping up as Paris Hilton's best pal by diverting female attention away from rocker Benji Madden.
Nicole - who is dating Benji's twin brother Joel - has been batting away blonde babes from the Good Charlotte frontman following his split from Paris.
A source says, "Benji was approached by dozens of ladies. Girls were trying to flirt with him . . . but Nicole kept getting in the way."
Benji and Paris split last week with a heart broken Paris waiting only a few days before publicly declaring her undying love for her rocker ex.
Paris told The Sun, “Just the thought of dating someone else grosses me out. No way.”
