Lady Gaga performed at the final presidential inaugural ball.

Wearing a stunning form-fitting white Versace gown, Lady Gaga performed at an inaugural ball for Obama’s campaign staff. Among the songs she sang at the Washington Convention Center were "Edge of Glory" and “Born This Way.”


She was then joined by Tony Bennett, who has won 17 Grammy Awards over the course of his career. The duo sang “The Lady Is a Tramp.” They first collaborated in 2011 on the classic song. 


Lady Gaga did not reveal much about the private Tuesday night event, simply tweeting, "#whitehausball."

President Obama and Vice President Biden joined in the festivities. According to the Washington Post, Obama told the more than 10,000 attendees, “It makes me know that America’s future is in good hands, as long as all of you understand the immense and incredible power that you possess when you work together when you join voices.”

The previous night, the president and first lady partied with a host of celebrity friends after leaving the inauguration ball. 

The Obamas and their guests reportedly stayed into the wee hours of the morning, and took advantage of several photo ops that were shared via Instagram and Twitter by attendees.

“I don't even know what to say. It's 3:15am and I just teared up seeing our president getting down at the white house,” John Legend's model girlfriend, Chrissy Teigen, tweeted.


Kelly Clarkson, who performed “My Country, Tis of Thee,” at the inauguration ceremony that morning attended the after-party with her fiancé, Brandon Blackstock, and wore a floral Oscar De La Renta gown. She shared a photo of herself and Blackstock in their “fancy” attire.


“Just partied at the White House. I kid you not, Michelle Obama stood up and got the party started ... seriously cool First Lady,” Clarkson tweeted as she left around midnight.
