Bethenny Frankel, who got engaged to her boyfriend Jason Hoppy earlier this month, is pregnant with her first child she tells PEOPLE exclusively.

Although The Real Housewives of New York City star had hoped to wait until she was further along to break the news, online buzz caused her to reveal that she’s roughly two months pregnant. “It’s premature to be telling people this,” she tells People.

As for getting pregnant before tying the knot, she says, “I’m no spring chicken. I didn’t think it was going to happen right away. Because of my age, sometimes we weren’t totally careful.”

But she admits, “I got to be honest, we are both feeling kind of proud of ourselves. We are both 38 and we were like, ‘Listen, your fish can swim and I am fertile.’ So that’s exciting.”
