Adele is booked to play at Kate Middleton's birthday party when the Duchess of Cambridge turns 34 in January.
The "Hello" singer, who recently announced she is going on a UK tour next year, will hold a private performance for the Duchess who is said to be a fan of the Grammy Award-winning singer and songwriter.
The Duchess' personal assistant contacted the crooner's management team at Middleton's request, and the singer immediately agreed to the booking, saying she would be honored to perform for the Duchess of Cambridge, Yahoo wrote.
Adele, who has admitted to being a fan of Prince William and his wife, will reportedly make changes in her schedule to accommodate the royal booking.
Middleton is said to be throwing a small royal soiree for family and close friends at the Norfolk Amner Hall home she shares with her husband, Britain's second in line to the throne, the Detroit News said.
Adele, whose third studio album, "25" broke sales records in the U.S. and UK when it was released last month, will be singing acoustic versions of the songs in her album, including a number of her previous hits at the soiree.
Her "Adele Live 2016" concert tour is scheduled to begin in Belfast, Northern Ireland on Feb. 29 next year, and will conclude in Antwerp, Belgium on June 15.
The UK tour, which immediately sold out in a majority of venues after sales opened two weeks ago, will feature the songs on the "25" album, including its lead single, "Hello."
