Lily Allen and Muppets characters Kermit and Miss Piggy will make an appearance at Robbie Williams' forthcoming London Palladium show.

The singer is performing at the venue on November 8 as he promotes his upcoming album 'Swings Both Ways', which will be released on November 18.

The event will be filmed for BBC One and it will see Williams play songs from the new swing album.

Lily Allen - who appears on the record  - will perform on the night, as well as fellow collaborator Rufus Wainwright.

Kermit the Frog and Miss Piggy will also show up, with the latter commenting:

"Moi is always thrilled to perform at the Palladium, no matter who I have to share the stage with. But being up there with moi's dear friend Robbie Williams and Kermie will make this night even more spectacular!"

Limited tickets for the event will be available on Monday (October 28) via Williams' official website.
