Aguilera performed in front of Barack and Michelle Obama, as well as their daughters Malia and Sasha, to celebrate the opening of the former US President's 19-acre presidential centre on Chicago's South Side.

The Genie in a Bottle singer was introduced by former Obama adviser Valerie Jarrett – who revealed that they had asked her to sing "one of President Obama's favourite songs", but the Grammy-winning star told them she had never sung What a Wonderful World in public previously.

However, Jarrett revealed that Aguilera "came up with a new arrangement" for the event.

Previous Obama Support

Aguilera has previously shown her support for Obama, including hosting a $1 million Democratic fundraiser that lauded the former White House chief's record in 2015.

Three years later, the Ain't No Other Man popstar performed at a Democratic National Committee (DNC) event, billed as an 'Evening with Barack Obama', at a private residence in Beverly Hills.

'Now we start writing a new chapter'

The Obama family was sitting in the audience with former White House occupants Bill and Hillary Clinton and George W. and Laura Bush.

The 44th president's new centre in the city where he formerly lived features an eight-storey museum, a replica Oval Office, an NBA-regulation basketball court, community gardens and a branch of the Chicago Public Library.

In an introductory video, Obama spoke about what Chicago means to him. He said it is where he "started knocking on doors, where I learned to listen and found my voice, where I fell in love with Michelle and built a family and a community and a home".

Obama added, "From this place, our circle and our aspirations grew, because the story of the South Side has always been a story and a possibility, and now we start writing a new chapter."
