Rap newcomer A$AP Rocky has signed on to play assassinated President John F. Kennedy as an African-American in Lana Del Rey's bizarre new video for National Anthem.

Del Rey will portray Kennedy's wife Jackie in the odd promo, which the hip-hop star describes as "some cool trippy s**t."

He claims his video partner's vision for the short film is way ahead of its time, adding, "People are gonna get it in, like, three years (and) that's the whole purpose of it."
