Alaskan baby daddy Levi Johnston, former fiancé of Bristol Palin and father of their child, has another baby on the way and plans to name her after his favorite pistol.

Johnston said he and girlfriend Sunny Oglesby would name their baby "Breeze Beretta," after the Italian handgun.

In an interview set to air tonight on Inside Edition, 21-year-old Johnston and Oglesby confirmed the baby would be named Beretta, "like the gun."

Johnston, an avid hunter, who once bared more than his arms for Playgirl, lifted his shirt sleeve to display a freshly-inked tattoo with the girl's first name "Breeze" written across his bicep.

Oglesby told Inside Edition her pregnancy was unplanned, the result of several days together in a wilderness cabin without any birth control.

"We were out at the cabin for like, four days, and forgot the birth control," she said.

Johnston said he planned to play a bigger part in Breeze Beretta's life than he does in that of his son Tripp, the 3-year-old he had with Bristol Palin. Johnston and Palin were high school sweethearts when she got pregnant.  Johnston and Bristol Palin became engaged soon after Gov. Palin was named John McCain's 2008 running mate. The couple did not marry.

"I'm actually in love… not doing it just because we had a kid together," Johnson told Inside Edition.

Bristol Palin, a one-time "Dancing with the Stars" contestant and abstinence advocate, has criticized Johnston for failing to pay child support and for being an absentee dad.
