Hilary Duff Reunites with Madden Brothers at MSG on Aug 5

Pop star Hilary Duff reunited with her ex-boyfriend Joel Madden and his brother Benji for a surprise performance with their band Good Charlotte during her sold-out concert at Madison Square Garden in New York City on Wednesday, August 5. The nostalgic moment, which saw the trio perform the band's 2002 hit "The Anthem," was a highlight of Duff's "Lucky Me Tour" and underscored the friendly relationship she has maintained with the Madden family since her high-profile relationship with Joel ended nearly two decades ago.

The surprise occurred during the first of Duff's two-night engagement at the iconic arena. After performing her new song "Adult Size Medium," Duff told the excited crowd she had a surprise, asking them to welcome her friends Good Charlotte. The Madden brothers joined her on stage, where they embraced before launching into the pop-punk anthem, with Duff singing the second verse. She had subtly teased the appearance earlier in the show by wearing an oversized vintage Good Charlotte T-shirt.

Duff, 38, and Joel Madden, 47, dated from 2004 to 2006. Their relationship was also professional, with the Madden brothers co-writing and producing Duff's 2005 singles "Wake Up"...
