Adele is set to perform at Michelle Obama's birthday next year.

The 'Skyfall' singer - who won Best Original Song at the Academy Awards last month - will reportedly join a string of other entertainers including Beyonce to help celebrate the US First Lady's 50th birthday bash at the White House in Washington DC on January 17, 2014.

A source told the ''America's First Lady will be holding a huge celebrity-packed party for her birthday at the White House next year and, as she adores Adele and Beyonce, she has asked them both to sing.

''Adele has graciously accepted and waived her usual fee for the high-profile private performance. She will sing a selection of her most-loved hits for the First Lady and her friends. The Obamas will pay Adele's expenses as it's a private party, not a State one.''

The 24-year-old British singer wowed the audience with a paired down performance of 'Skyfall' at the Oscars last month, her first live performance since giving birth last October.

She was previously said to have celebrated her prestigious win by presenting her five-month old son Angelo with his very own mock statue of an Academy Award from a souvenir shop.

She posted a picture of her coveted award on Twitter alongside the joke gong, adding the caption: ''and we're home! What an epic trip. Thanks for having us Hollywood!''

The baby boy - who Adele has with her boyfriend Simon Konecki - travelled to Los Angeles with her for the star-studded show.
