McCartney Video Sign Language Errors?

Looks like there may have been a bit of error in translation with some of the sign language in a Paul McCartney video. For his new music video “My Valentine,” Paul McCartney enlisted the aid of Natalie Portman and Johnny Depp to interpret the lyrics of his song through sign language. However, some in the sign-language community are now claiming the actors botched the effort. The video, released on April 13, came in three editions: one with Portman, one with Depp, and one splicing the two together. According to UK tabloid The Sun, both actors signed the word “tampon” instead of "appear," and Depp additionally signed "enemy" while attempting “valentine.” What's next? Calling patio furniture something like pancake? Well done on the editing people. Enemy and Valentine though could be quite compatible no? Certainly wouldn't want a tampon to appear from anywhere though if I could help it.
