Levi Johnston Weds Baby Mama Sunny Oglesby

Levi Johnston has finally made an honest woman out of the mother of his latest child -- the couple got hitched in Alaska today ... TMZ has learned.

According to our sources, Johnston and girlfriend Sunny Oglesby exchanged vows in front of more than 100 friends and family. But according to our sources ... Tripp, the son he shares with Bristol Palin, was not in attendance.

Levi and Sunny might want to get their money back from the printer who made up the invitations (above) -- the word "famalies" ... well, it's just not a word.

As TMZ first reported, Oglesby gave birth to the couple's first child, Breeze Beretta Johnston, last month.
