A new preview clip has been released featuring David Beckham in a special episode of Only Fools And Horses.

Beckham appears alongside Sir David Jason and Nicholas Lyndhurst in the one-off special, which will be shown in full during this year's Sport Relief.

In the new clip Del Boy is seen rolling his eyes after Becks wrongly says "incognitive" instead of "incognito".

Del Boy star Sir David revealed earlier this week that it was Becks' idea to revive the classic comedy for Sport Relief.

He told The Michael McIntyre Show: "He said he had always loved Only Fools And Horses and that it would be great to do something with me and Nick. So then the grapevine started to work as these things do."

The actor also admitted that he didn't think the show would return following the death of its creator John Sullivan, however, he was happy to sign up after reading the script.

He told the chatshow host: "Once I read the script that they intended to do, and I said yes I would do it, it was so much of Sullivan and so much of Only Fools And Horses the original, that I said, 'Yes, let's do it'.

"When I got together with Nick (Nicholas Lyndhurst, who plays Rodney) for the first run-through it came back like that (clicks fingers). I didn't even have to think about it.

"It’s like anything, it’s like falling off a log. As soon as I put on the gear and started to look at the script, back it came."

However, it wasn't such plain-sailing for footballer Becks, who admitted that he found the experience nerve-wracking.

He told Radio Times: "The day of filming started off with a slightly sleepless night, going over my script. The thought of being on set with Nicholas and David was obviously very nerve-racking."

Sport Relief is on BBC One on Friday 21 March.
