"I judged a book by its cover."

Priyanka Chopra Jonas is getting real about the start of her relationship with Nick Jonas.

On Thursday, the 36-year-old actress spoke at Tina Brown's 10th Annual Women in the World Summit in New York City, and revealed why she never thought she'd end up with her now husband.

"I’ve known him for two years. I didn't think that this is what it turned out to be, and that's maybe that’s my fault, I judged a book by its cover," she admitted. "When I actually started dating Nick he surprised me so much... I call him Old Man Jonas. That's my name for him, OMJ. He’s such an old soul, extremely smart, so good for me because he grounds me so much. I'm a wild child. I do whatever I want whenever I want and he always supports me."

Priyanka also spoke to how Nick's support of her career made her reevaluate her first impression of him. 

"One of the things that first struck me about him was we were on a date and it was time for the date to get over, we were [with] a bunch of friends, and I had a meeting... and I was dropping hints to my friends and they were like, 'No, don't go for the meeting. Just stay,'" Priyanka recalled. "And I was like 'No, no, no. If someone gives me reason enough to cancel it, I'll cancel it.' And he just didn't pick up the hint. I said it twice. I said it thrice."

"Finally he took me aside and was like, 'Look, I'm not stupid. I know what you're trying to do. But I would never be the one to tell you to cancel work because I know how hard you've worked to be where you are. So, if you could've canceled it, you would've done it. I'll take our friends out for dinner and we'll wait for you and you finish your meeting and come back,'" she continued. "And I was just like, 'That's the first time someone's ever done that.'"

The pair also get on well because they share a similar interest in charity work.

"Nick has always been philanthropic... we come from a family where philanthropy is not a choice -- it's just what you do, it's second nature," she explained. "... We've discussed many things that we want to do together, and we know we have the ability to. It's in fact our favorite phrase, that we want to change the world in whatever way we can."

In addition to all the reasons they work well together, Priyanka talked about the culmination of their love story -- their extravagant, multi-day weddings.

"Hopefully it will be the only one," she quipped. "I knew it was going to be three days because Indian weddings do have pre-rituals. And I knew that both of us wanted one wedding in each of our religions, so that was two days anyway."

"It all happened so fast. We decided to prep this wedding in October, and we got married the first of December," she explained. "And in that one and a half months we were like, 'Yeah, that sounds great! Sure, let's get that!' And did not realize it until it was done. We saw videos, and then the bill. And we were like, 'Cool cool, maybe we should have prepared this a little bit more.' So that's why it was so glorious."
