Christina Aguilera dressed to impress at the opening of the Obama Presidential Center.
The superstar singer wore a semi-sheer Prabal Gurung dress with a long train while performing Louis Armstrong’s “What a Wonderful World” in Chicago on Thursday.
The 45-year-old opted for minimalist jewelry, a silver ring on her right finger and her signature blonde hair curled underneath.
Aguilera performed in front of Barack and Michelle Obama and their two daughters to celebrate the opening of the former president’s new 19-acre Presidential Center on Chicago’s South Side.
Former Obama adviser Valerie Jarrett introduced Aguilera and said she had been asked to sing “one of President Obama’s favorite songs,” but the Grammy winner shared that she had never performed “It’s a Wonderful World” in public before.
But Aguilera “came up with a new arrangement” for the event, Jarrett said.
Aguilera has supported Barack, 64, in the past, including in 2015 when she hosted a $1 million Democratic fundraiser praising the Obama administration’s accomplishments.
Three years later, the “Beautiful” singer performed at a Democratic National Committee (DNC) event billed as “An Evening with Barack Obama” at a private residence in Beverly Hills.
In the last presidential election, Aguilera openly supported Kamala Harris over eventual winner Donald Trump.
Other performers on Thursday included Jennifer Hudson, who sang the national anthem and a cover of “For a Dream,” followed by The Roots, John Legend, Marc Anthony and U2.
Pearl Jam’s Eddie Vedder also took to the stage, and he was joined by young members of the nonprofit organization Guitars Over Guns.
Many stars appeared at the opening, including Oprah, Steven Spielberg, George Lucas, Tom Hanks, Stephen Colbert, David Letterman, Conan O’Brien, Anne Hathaway, Gabrielle Union, Quinta Branson, and Mark Hamill.
The Obamas sat in the audience along with Bill and Hillary Clinton and George W. Bush and Laura Bush.
Located in the city’s former home of the 44th president, the new center includes an eight-story museum, a replica of the Oval Office, an NBA regulation basketball court, a community garden and a branch of the Chicago Public Library.
In his introductory video, Barak talked about what Chicago’s South Side means to him.
That’s “where I started knocking on doors, where I learned to listen, where I found my voice, where I fell in love with Michelle, where I built a family, a community, a home,” he said.
“From this place, our circle and our aspirations have grown, because the story of the South Side has always been a story and a possibility, and now we are beginning to write a new chapter,” he said.
The center will officially open to the public on Friday.
