Heidi Montag stopped by TRL yesterday to promote her new clothing line and of course, The Hills. Things between Spencer and Heidi were pretty rocky due to their "relationship vacation" on last night's episode, but we know how that story ends. Speaking of last night, were you paying attention to all of the fashion, gadgets, and beauty looks that the girls were rockin'? Perhaps now that some of her Spencer stress is relieved, Heidi can finally find the time to register to vote in support of her candidate John McCain? Even if you don't want to dress like Heidi, at least getting involved in the presidential election is a good example to follow.
