Shannon Elizabeth & Derek Hough, Season 6: Derek Hough tends to have great chemistry with all his partners, but he had something even stronger with his Season 6 star, “American Pie” actress Shannon Elizabeth. She was the seventh star sent home that season, but she and Derek continued to tango for more than a year before announcing their breakup via Twitter in August 2009. Derek’s Twitter message read, “Hi everyone, we wanted you all to know directly from us, that Shannon & I have decided to end our relationship as boyfriend & girlfriend …” and Shannon’s second message, which concluded the chain, said, “however, we love & care about each other very much & will remain friends & in each other’s lives.”
