Kick-Ass star Chloe Grace Moretz has dedicated Wednesday night's (26Mar14) performance onstage in Broadway play The Library to her late grandmother.

The actress' ailing relative passed away on Wednesday and her granddaughter marked her death with a photo tribute on Instagram.com.

Moretz posted several pictures of her late "Memom" on the site and added the caption, "You will never be forgotten Memom, I love you more than you can ever imagine. And tonight I will perform on that stage for you. May 24, 1929 - March 26, 2014."

The actress began previews for the new Steven Soderbergh production on Tuesday (25Mar14).
