In the picture, the couple is enjoying a spaghetti dinner with a bottle of Prego marinara sauce. Taped to the sauce bottle is the word "we're," reading, "We're Prego."
Johnston first made headlines during the presidential election in 2008 when vice presidential candidate Sarah Palin announced that her then-teenage daughter was expecting a baby with then-fiance Johnston.
The couple welcomed son Tripp in Dec. 2008 and split soon after, only to rekindle the flame in 2010. But that romance was short-lived and they split for good in August 2010.
Johnston married Oglesby in Oct. 2012, one month after the couple welcomed daughter Breeze. They now live in Wasilla, Alaska.
