Lil Yachty’s celebrating a major life milestone — and likely losing sleep — because he’s on daddy duty now!!!

Sources with direct knowledge tell the “Yacht Club” rapper is father to a baby girl who was born in the last couple weeks in New York City.

We’re told Lil Yachty is in the Big Apple right now, where he’s spending some time with the child.

It’s unclear who the mom is … to us, anyway. Obviously, Yachty knows, but he has had a few different girlfriends recently. Stay tuned.

We reached out to his reps, but so far … no word back.

Congrats, Yachty, enjoy being a #GirlDad!!!
