Celine Dion

After buying a house with a tennis court attached, Jonathan Ross developed a love of the game that finds him knocking up with a comedy coterie including Michael McIntyre, Jimmy Carr and David Baddiel. Tips from a Wimbledon champion are quite another thing, though, and having predicted that Andy Murray would triumph earlier this year, Ross welcomes him to the sofa to relive his glories.

They're joined by Celine Dion, whose new studio album Loved Me Back To Life is her first big English-language release since 2007. Perhaps unfairly, neither Murray nor Dion are known for their comedy punchlines, so Johnny Vegas and John Barrowman will be bringing the funny.
