How I Met Selena

Fans should have known that only a strong, Latina triple-threat might break How I Met Your Mother's Barney Stinson (Neil Patrick Harris) of his womanizing ways. In an upcoming March episode of the sitcom, Jennifer Lopez will guest star as Anita Appleby, a self-help author enlisted by Robin to get Barney to shed his Bro Code (perhaps in favor of gelled hair and flashy music videos parodying his paparazzi-plagued lifestyle?).
