Presidents and First Ladies at Inaugurations | Pictures

On Jan. 21, Barack Obama will be sworn in publicly for his second term as president of the United States alongside First Lady Michelle, after being privately sworn in on Jan. 20. And we can't wait to see these two lovebirds all dolled up for the festivities. In the meantime, we're taking a look back at some of the most adorable first-couple moments from past inaugurations (including Michelle and Barack's first one in 2009). After the stress of an election, Inauguration Day has given presidential power couples a chance to bask in the joy, and relief, of a big electoral win — and their happiness shows in the charming dances and proud glances. Before we check out the always-affectionate first couple, Michelle and Barack, at this year's inauguration, let's take a look back at sweet inauguration PDA over the years!
