Natalie Portman used incorrect sign language in Macca promo

Johnny Depp and Natalie Portman have been shamed by deaf music fans for using incorrect sign language gestures in Sir Paul McCartney's latest music video.

The Beatles legend recruited the Hollywood stars to sign the lyrics to his track My Valentine in a black-and-white promo directed by McCartney himself.

However, deaf devotees have now pointed out errors made by the actors - Portman signs the word 'tampon' instead of 'appear', while Depp makes the motion for 'enemy' while attempting 'valentine'.

However, a representative for The British Deaf Association has heaped praise on the duo for their efforts.

A spokesperson says, "It's great that famous people such as Johnny Depp and Natalie Portman are highlighting the use of sign language. Their use of it is more a poetic expression.

"The sign for tampon does seem to come up from both Johnny and Natalie, which causes some confusion, especially as American and British sign languages are different.

"It would have been nice if genuine deaf people had been used. But it's still great."
