"Whether in his work or his personal life John was extremely loyal," the Downton Abbey star said Wednesday at St. James' Church in Ballinora. "It was clear that when John was in your corner he was there. I was honored to know John. To love him and be loved by him. He was my friend, my king, my hero, my everything. We celebrate him, we honor him and we will miss him."
Dockery was introduced to Dineen by her Downton co-star Allen Leech in 2013, and the public relations executive was diagnosed with a rare form of cancer earlier this year. Dineen passed away on Sunday, two days before Dockery's 34th birthday and four days prior to what would have been Dineen's 35th birthday.
"John's charm was legendary. He could persuade anyone to do what he wanted in the least pushy way possible. Particularly the women," Dockery continued. "He had a presence that was electric when he came in to the room. He had a wicked sense of humor. He had a genuine interest in other people."
In addition to speaking, Dockery reportedly sang Dineen's favorite song, Oscar Hammerstein's "The Folks Who Live on the Hill," as part of the service.
