Sir Paul McCartney calls Gavin & Stacey star James Corden a “bloater” in a special new sketch for Comic Relief.
The former Beatle is one of a host of guest stars who give Corden – playing his TV character Smithy – advice on whether he should go to Africa.
In the skit, Sir Paul says: "People don't like seeing tubby people over in Africa. If they hadn't eaten so much, no one would be starving."
Other celebrities include David Beckham, Keira Knightley, George Michael and Harry Potter star Rupert Grint, reports The Sun.
Campaigning for this year's Comic Relief starts on Thursday (February 3). The live telethon will be broadcast on the BBC on March 18.
As previously reported on Gigwise, Corden has been named the controversial host of this year's BRIT Awards, which taken place in London next month.
