Just in time for Mother’s Day, Bethenny Frankel is a new mom!

The Real Housewives of New York City star and her husband Jason Hoppy welcomed a baby girl Saturday, her rep confirms to PEOPLE.

“Bethenny and Jason are proud to welcome their new baby girl, Bryn Hoppy, born at 8 a.m. . . . in New York City,” the rep says. “She is a 4 lb. 12 oz., healthy baby. Bryn, mom, dad and [their dog] Cookie are all very happy.”

Frankel and Hoppy, who were married March 28, were surprised to know the baby’s sex. “Jason won’t let me find out because he knows I’ll spoil it,” she told PEOPLE in an interview about her pregnancy.

She did, however, Tweet, “I had a dream it was a girl.”

So, it seems, dreams do come true!
