Two Marines got married in Ripley, in upstate New York on Saturday . . . a Sergeant named Joshua Newville and a Senior Airman named Emily Leehan. And Joshua has a four-year-old son named Gage from a previous relationship.
Well . . . during the ceremony, while Emily was saying her vows, she called Gage up to say a few things to him.
And when she started talking about their future as a stepmom and stepson, Gage was OVERWHELMED . . . and he started crying and hugging her.
The video of the moment is now going viral.
Emily says she included Gage because, quote, "When I was vowing to be Josh's wife, I was also vowing to be his stepmom. I wanted him to feel special and to remind him of how much he means to me."
Joshua and Emily are both still on active duty, so now they're back at their base in New York . . . with Gage, and a whole unexpected level of viral fame.
