Levi Johnston, Bristol Palin's ex-boyfriend and father of her son Tripp, is set to marry his girlfriend Sunny Oglesby this weekend.
The couple will tie the knot after dating "for about a year and a quarter," a source told Us Weekly.
Johnston and Oglesby welcomed a daughter, Breeze Beretta, in September 2012. Palin wished the couple "the best" despite having a rocky past with Johnston, including more than one breakup and a custody battle over their son.
"Sent them some flowers today when I heard the news!" Palin said after the birth of Johnston's daughter. "Wish them the best, Tripp will be excited to hold her!"
