Reality TV stars Heidi Montag and Spencer Pratt - the latter being Brody Jenner's, uh, "manager" - were caught shopping at Target a few days back. So our photog asked the allegedly engaged, media-loving couple, "When's the big wedding?" Spencer replied with "I dunno, who's getting married?" Then Heidi laughed. Golly, they ARE good actors! Can't wait for season three of The Hills! (Not.)
