Mandy Moore isn't letting any mom group drama keep her from giving her friend Hilary Duff her flowers. "Broke my brick time to say that my bud is a sensational icon queen, giving us all what we needed," Moore, 41, wrote via her Instagram Stories, sharing footage from Duff's Thursday, January 29, intimate concert in Los Angeles. "You are forever a superstar!" Moore later pointed out in follow-up footage that Duff's new single "Mature" is her favorite song. "@MatthewKoma [and] @TaylorDawesGoldsmith grooving out," she wrote, alongside a video of the two women's husbands dancing in the crowd.
