's new girlfriend just popped ... we found out she just gave birth to a healthy baby girl in Wasilla, Alaska ... and the kid's name -- Breeze Beretta Johnston.

As we first reported, Levi and his girl Sunny Oglesby did NOT plan the pregnancy -- but they're both down with it now.

Breeze Beretta was born at 5:28 AM at Matsu Regional Hospital. She's 6 pounds 15 ounces and, at 19 inches, considerably longer than the standard-issue Beretta.

Breeze is Levi's second child. His ex Bristol Palin gave birth to their son Tripp in 2008.

All hail the new Team Breezy.
