During an interview with Howard Stern on SiriusXM on Tuesday, Downey said that instead of doing the usual routine while in New York on a recent trip, he decided to take care of some “personal business.”

“I wanna check in with someone I shared a big part of my life with and say hi,” he told Stern.

Downey Jr. and Parker dated for seven years before calling it quits in 1991.

The “Iron Man” actor, 50, went on to marry and divorce Deborah Falconer and then married his current wife, Susan, in 2005. Parker, also 50, married fellow actor Matthew Broderick in 1997.

Downey Jr. and Parker met at the former “Sex and the City” star’s apartment, where she introduced him to her children.

“We were able to spend some time together and it was really cool,” he told Stern.

“You know, the funny thing too is you always have a perception of somebody that you spent a big chunk of your life with and I think it’s typical to the human thing that the further you get away from that in your new relationship, you sub-intentionally taint your perception of the person.

“Seeing her I was like, ‘She’s so great and so cool and so funny and so in command.’”

He says he met her kids and saw the way “she and Matthew live and I respect both of them so much.”

He also shared his deep admiration and respect for Broderick, who wasn’t around for the meeting.

“I would have loved to have seen him,” Downey Jr. added.

“For my generation, particularly the New York theatre guys, he was the beginning and ending of everything you could aspire to be.”
