Celebrity Couples: The Top 13 of 2013
William Tell and Lauren Conrad
After celebrating their one-year anniversary on Valentine's Day, the former Hills star and the Something Corporate rocker turned USC law student got engaged in October. Tell had only recently moved in with the Paper Crown fashion designer -- whose exes include Stephen Colletti, Brody Jenner, and Kyle Howard -- but he knew he wanted to marry her. And the feeling was mutual. "If you're going to settle down, it should be with someone you can't stop thinking about," Conrad told Cosmo of her fiance.
