The Real Girls Kitchen host and fiancé Matt Rosenberg welcomed their first child, daughter Ryan Ava Erhard Rosenberg, on Monday, May 11, in Los Angeles, her rep confirms to PEOPLE.

“We are on cloud nine and so happy she is finally here! Thank you to everyone for all of their love, support & well wishes!” the new parents tell PEOPLE.

“Both mom and baby are doing great,” her rep says. “Haylie and Matt are thrilled to finally meet their baby girl and become a family of three.”

Added Duff Wednesday via Twitter, “What an exciting, love filled couple days! So happy to finally bring home the newest lil member of our family!”

After her December announcement that she was pregnant with a daughter, Duff, 30, and Rosenberg shifted their focus from wedding planning to preparing for parenthood.

But the thought of one day having their daughter present for their wedding was “pretty cool,” the mom-to-be told PEOPLE days after her pregnancy reveal.

Following a rough first trimester filled with naps, Duff experienced a surge of energy in her second trimester, which she took advantage of by exercising every day.

In March, the actress was showered with love from friends and family — including sister Hilary Duff — at her floral-themed baby bash.

“Haylie was on cloud nine. She is so excited to be a mom — you could see it all over her face!” a source told PEOPLE after the party.

And although she delighted in buying things for her baby girl, Duff did try to hold out on one thing: maternity wear.

“I was fighting the good fight on buying maternity clothes, but now I just have this massive belly and I can’t deny that I’m pregnant any longer!” she told PEOPLE in February.

“I’ve tried to not go too maternity, but at a certain point you’ve got to have room.”

E! News was the first to report the birth.
