The Susbstance star, 31, started the rumour mill churning on Friday when she failed to appear at Taylor's wedding, despite her husband, rocking up in his tux, with sister Rachel as his plus one instead. The 42-year-old Grammy-winning producer - who has worked with Taylor on some of her biggest albums – put on a brave face despite Margaret not joining him to the star-studded wedding, which brought New York to a standstill at Maddison Square Garden. After Margaret's surprise no-show, rumours were rife over why she missed the ceremony, with some suggesting she was unwell or had even fallen out with the bride. However, it now appears trouble brewing for some time between the actress and her husband, with one wedding guest claiming they overheard the multi-millionaire talking about a row the couple had recently had.
