Rory Culkin has welcomed his first child with girlfriend Kate Arizmendi, a baby girl, becoming a father for the first time on the date of the article. The couple are now first-time parents.

The news marks a new chapter for Culkin and Arizmendi, whose child is identified as a girl. For the pair, the moment is simple and immediate: they are no longer expecting, and the next stage of family life has begun.

That is the full story today. Culkin and Arizmendi have joined the ranks of first-time parents, and the detail that matters most is also the most personal — their child is a daughter. No other context changes that fact, and nothing else is needed to understand why the news lands now.

For Culkin, the arrival turns a private milestone into a public one, but the center of the story remains the same: a first child, a baby girl, and two people stepping into parenthood together for the first time.
