AceShowbiz - Also ended up dating the same guy were Lindsay Lohan and Hilary Duff. Hilary first dated Aaron Carter for more than a year in 2000 before he overlapped their relationship by romancing the "Mean Girls" leading lady. The pop singer himself admitted that he was seeing Lindsay because he was bored of what he had with the former "Lizzie McGuire" star.

Although both of them were no longer with Aaron by 2003, the beef between Hilary and Lindsay remained. Things got worse in the following year after Rachel Dratch dressed as Hilary during Lindsay's "Saturday Night Live" hosting gig, prompting the "Gossip Girl" alum to slam her nemesis, saying, "I'm not here to talk bad about her like she talks bad about me all the time." In 2007, however, Hilary made it clear that their spat was over. "We are both adults, and whatever happened, happened when we were young," she declared.
