The Napoleon Dynamite star and her fiance Matt Rosenburg welcomed a baby girl named Ryan on Monday (11May15), reports E! News.

The couple got engaged in April last year (14) but put off wedding planning when they discovered Duff, 30, was pregnant.

Duff, the sister of singer/actress Hilary, told at the time, "It was kind of too much to all do at once... We're just trying to focus on one thing first, and then we'll do it."
