According to one website, Shatner also added that actor's death was so upsetting, but also really lovely to see how loved Nimoy was and will continue to be.

Shatner also shared a photograph of the two on the website Who Say and fans were quick to comment on the post.

Nimoy died at his home in the Bel Air section of Los Angeles, after being rushed to hospital after suffering from severe chest pain last week.
