Bruce Forsyth will perform with Ant and Dec at the National Television Awards tonight.
The legendary 'Strictly Come Dancing' host and the presenting duo will sing Nat King Cole's 'Let There Be Love' at the opening of the show at London's O2 arena this evening and rehearsals at the Duke Meadows studios in West London have reportedly been "great".
A source hinted at the performers, telling The Sun newspaper: "Brucie has agreed to perform a song from his new album as he said he's always wanted to play the 02.
"He'll be joined by two very special faces from the TV industry that most people should know. If I were a telly fan I'd be sure to join in."
Another source told the Daily Mirror newspaper: "Rehearsals sounded great. There was a bit of a crowd gathering to listen when word got around they were in the studio.
"Nobody could work out why those three celebrities would be working together on something. It was a huge shock."
Ant and Dec are up for an award for Best Entertainment Presenter for the 11th time while Bruce will be hoping 'Strictly Come Dancing' picks up the Favourite Talent Show award.
