Macca joins Leona Lewis, Muse, Lily Allen, Dizzee Rascal, Snow Patrol and Dame Shirley Bassey for the November 12 show at London's Royal Albert Hall.
Organiser Gary Barlow also told the Mirror that Robbie Williams is a surprise guest.
He added: "I have asked Robbie to perform with us. It would be great to get back together on stage for charity.
"Having a big name like Robbie's would definitely help us sell tickets and raise a lot more money for charity."
Gary had been due to make the announcement a t yesterday's launch, but had to cancel following the sudden death of his father Colin.
Tickets, priced £50 to £100, will be allocated by ballot. Fans can buy up to two each and have until Tuesday to register at bbc.co.uk/pudsey.
The show will be broadcast on BBC1 in November.
