Sunny Oglesby and Levi Johnston's sister Mercede.

Sad news for Mama Grizzlies everywhere: Levi Johnston is a married man. 

Bristol Palin's ex-fiance said "I do" Sunday evening to Sunny Oglesby in Alaska in front of over 100 close friends and family members, Us Weekly reports.

"Congrats to my Brother Levi and his lovely bride Sunny," Johnston's sister, Mercede, tweeted, and proceeded to post photos of the groom and new sister-in-law.

Levi and Sunny, a 20-year-old teacher, welcomed daughter Breeze Beretta, named after the firearm, in September. Levi, 22, also has a 4-year-old son, Tripp, from his relationship with Bristol.

Bristol eliminated from "Dancing With the Stars"

And while Sarah Palin's "Dancing With the Stars" daughter and Levi have had a contentious relationship in the past, they seem to have patched things up. When Levi and Sunny welcomed baby Breeze, Bristol told E! News she "sent them some flowers today when I heard the news!"

Bristol also said she "(wishes) them the best. Tripp will be excited to hold her!"

Congratulations all around.

Levi Johnston.

With the birth of his second child, Levi Johnston celebrated his Constitutional right to bear .... babies named after arms.

TMZ reports the Alaska native's girlfriend, Sunny Oglesby, gave birth to Johnston's second child Wednesday, a daughter named Breeze Beretta Johnston -- with the unusual middle name referencing the Italian firearm manufacturer. (Johnston, 22, is already a father to Tripp Palin, his 3-year-old son with ex-fiancee Bristol).

In April, Johnston and Oglesby sat down for a chat with "Inside Edition," during which he admitted the pregnancy was "unplanned."

"There was a time we went to the cabin and forgot the birth control pills, and a month later we found out we were having a baby," he explained of Sunny, a 20-year-old teacher who resides in his hometown of Wasilla, Alaska.

Johnston and his ex, the eldest child of former Alaska governor Sarah Palin, welcomed son Tripp in late 2008; the couple called off their engagement in March 2009, got engaged again in July 2010, but finally called it off for good just three months later.

"Bristol wanted to have a baby," Johnston sniped of Bristol, 21, to E! News in September 2011. "It all happened on purpose, and I was dumb enough just to roll with it."

Levi Johnston at the Teen Choice Awards in 2010.

He's not the Thrilla From Wasilla anymore. Bristol Palin's baby-daddy, Levi Johnston, is now penniless and living in his mother's Alaska home, a source tells Us Weekly.

"Levi made more than $1 million and squandered it on guns, boats and four-wheelers," the source says of Playgirl's winter 2010 cover model, 22.

The cash certainly didn't go to Palin, 21, for their 3-year-old, Tripp. "Levi hasn't paid child support in nearly two years," says another insider. "And he has little contact with Tripp."

Meanwhile, the onetime mayoral hopeful is expecting a daughter with girlfriend Sunny Oglesby. (They told Inside Edition they plan to name her Breeze Beretta, after the gun.) Says the first source, "Levi is confused about his life."

Levi Johnston's former rep Tank Jones -- with whom he recently parted ways -- counters that Levi is doing great.

"I wanted to work on other projects. This was a mutual decision," Jones tells Us of his decision to cease working with the Alaska native. "I would think he would want to do some different things too. I would never leave him at a low point."
