Paul McCartney's My Valentine video is filled with sign language mistakes

Paul McCartney's My Valentine music video is littered with sign language mistakes, according to deaf fans.

The promo, which stars Hollywood heavyweights Johnny Depp and Natalie Portman, shows them using the wrong signs to illustrate certain words.

People with hearing difficulties claim that Black Swan star Portman made the first gaffe by signing the word "tampon" instead of "appear", followed by Depp signing "enemy" instead of the more appropriate "Valentine".

The three-minute video, which premiered at a screening in Los Angeles, has led to a backlash with many viewers posting comments highlighting the errors alongside the video on YouTube.

Despite the mistakes, the British Deaf Association still applauded McCartney's efforts.

A spokesman for the association told the Sun: ''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.''

The Beatles legend asked Hollywood stars including Gwyneth Paltrow, Gwen Stefani, Miranda Kerr and Reese Witherspoon to appear at the exclusive premiere of the video.

My Valentine is off McCartney's latest album, Kisses on the Bottom.
