Just a couple of years before her death, Elizabeth Taylor began a friendship with Colin Farrell that he admitted Monday felt like "the last kind of romantic relationship I had."

The two never "consummated" their relationship, Farrell told Ellen DeGeneres on her show.

But he met the "Cleopatra" actress in 2009 when Farrell's son, Henry, was being born, two years before Taylor died in 2011 at age 79.

The "Saving Mr. Banks" actor, 37, bumped into some friends of Taylor's at the hospital and told them, "Will you tell her I said hello? She probably won't know who I am."

But Taylor did know the "Total Recall" star and a few days later, Farrell called his publicist to see about sending her some flowers.

"And my publicist said, 'That's funny because I'm looking at an orchid from Elizabeth Taylor for you," he told DeGeneres. "I said, 'Wow that's amazing. Well, send that bad boy over to the house.'"

About a week later, he asked whether he could go see Taylor.

"I got to have an audience with her," he added. "'That was the beginning of a year and a half or two years of what was a really cool … feels like in my head, not her, I'm projecting, but the last kind of romantic relationship I had."

Farrell added that the two stars bonded over late-night calls.

"She's wasn't much of a sleeper at night, like I'm not, so at two o'clock in the morning I'd call her," he said. "I just adored her, she was a spectacular, spectacular woman."
