Hilary Duff and Joel Madden's Onstage Reunion Sparks Buzz 20 Years Later

Hilary Duff reunited onstage with her ex-boyfriend, Joel Madden, for a surprise performance at her sold-out “The Lucky Me” World Tour stop in New York City — two decades after they broke up.

The “So Yesterday” songstress sent fans into a frenzy after she changed into a Good Charlotte T-shirt midway through her performance at Madison Square Garden Wednesday night right before bringing out her special guests.

“New York, you know I would never come here and not have a surprise for you,” she told the audience, as they erupted in cheers.
