Levi Johnston, Bristol Palin's Ex, Welcomes Baby #4

Levi Johnston is a proud papa once again.

Johnston and wife Sunny Oglesby welcomed their third child together, Delta Jo Johnson, last week at Integrated Women's Wellness in Palmer, Alaska, the couple revealed to "Entertainment Tonight."

Delta weighed in at 7 pounds, 14 ounces and measured 21 inches long.

The couple was already parents to two other girls, Breeze and Indy, and Johnston had son Tripp with Bristol Palin back in 2008.

Johnston and Oglesby were married in 2012 and Breeze was born a month before the wedding. Indy was born three years later.

As The Blast first reported, Johnston was sued last year by an attorney who claimed that he owed money stemming from his custody battle with Bristol Palin.

The attorney claimed the former Palin fiancé owes $12,892.50 for all his services and alleged that Johnston continued to "refuse to pay."

The lawsuit was later dismissed.

Johnston and Palin had a bitter war over the custody situation with Tripp, mostly because Bristol claimed her baby daddy hadn't paid a dime in child support. They eventually got it all straightened out, and now have an order that gives Palin the majority of the time with 9-year-old Tripp, and Levi gets visitation. He claimed at the time that it cost over $100,000 in legal fees to hammer out the agreement between the two parents.
