President Obama & First Lady's First Dance

After Barak Obama was publicly sworn into his second term as President of the United States, the traditional festivities ensued in Washington D.C. The recently renewed President and First Lady Michelle Obama celebrated as all presidents and their wives do with their first dance.

ET was there as the First Lady and 44th U.S. President swayed hand-in-hand to the sweet soulful sounds of Jennifer Hudson's rendition of Al Green's "Let's Stay Together," a fitting song to cap the day after President Obama's repeated usage of the word "together" in his inauguration speech.

ET's correspondent Rocsi was live to narrate the scene, and caught up with music artist and entrepreneur will.i.am as well. A major advocate for STEM (science, technology, engineering, mathematics) education, the Black Eyed Peas front man said he's excited for what the President's second term will bring.

"This [inauguration is about] forward motion, moving America towards this united America...so we can get on track to compete twenty years from now with technology and get our kids encouraged and inspired to take a STEM skill set to where they want to be scientists and technicians, engineers, mathematicians, innovators and invent things in America again," he said passionately.
