Sarah Jessica Parker broke Robert Downey Jr.'s heart

ROBERT Downey Jr. admits he was heartbroken after his split from Sarah Jessica Parker.

The 'Iron Man 3' star, whose wife Susan Downey is currently expecting their second child, dated the 'Sex and the City' star for seven years after they met on the set of 'Firstborn' in 1984, but she dumped him in 1991 due to his severe drug addiction.  

Asked if the blonde beauty broke his heart, the 'Judge' star told Howard Stern on his Sirius XM radio show: "I've never been the kind of person to acknowledge what's going on with me at the time, and I'd try to make light of it, but sure, when you're with someone for seven years, 18 to our mid-20s, it's kind of a big deal."  

But the 49-year-old star insists there is no bad blood between him and Sarah, 49.  

He said: "No, no. In fact, I'll make a point of trying to see her while I'm here [in New York City]. I'd like to."   But Robert, who credits Susan and his late mother for helping him to get sober, plans to check with Sarah's husband, Matthew Broderick, before reaching out to her.  

He said: "I'll ask his permission. I just want to check in for a few minutes. I love Matthew Broderick.  

"First of all, I respect both of them so much, and now we have to get past this conversation. For any situation like this, I think enough time has to pass. You don't have to make a big deal of it when the time is right."  

He added: "I'd love to have him there. Maybe, I'll bring Susan."  

Sarah previously admitted she feared Robert would die after they broke up.  

She said: "The simple answer to why I stayed with him is that I loved him. I felt that if I left, he might die. I believed I was the person holding him together.  

"You're not even in a romantic relationship any more. It's like a parent-child thing."
