Colin Farrell was one of the few non-family members who attended Elizabeth Taylor's private funeral last week -- but why?

"How did we become friends? You know, the old story of boy meets girl, the boy pesters girl with too many phone calls at inappropriate hours of the night," Farrell, 34, tells Access Hollywood.

"I was just lucky enough to become her friend in the last year and a half," the actor added. "I adore her...still."

Taylor, who passed away of congestive heart failure at the age of 79, spoke of her fondness for Farrell in the March issue of Harper's Bazaar.

"I love Johnny Depp, and I love Colin Farrell," she told Kim Kardashian, who conducted the interview. "They're both brilliant, nuanced actors with great range."

As a result of their unlikely friendship, the Horrible Bosses actor was asked to recite Gerard Manley Hopkin's poem, "The Leaden Echo and the Golden Echo," at Taylor's funeral.

"Elizabeth chose it. It was a tricky poem as well," Farrell laughed. "Even in passing she had me under the thumb, sweating bricks."

Farrell admits he's still having a hard time coping with the loss of his friend. "I just miss her," he said.
