According to the Daily Dot, it's not the first time Hanks has crashed a wedding. He stopped to congratulate a couple while filming Forrest Gump in South Carolina in 1993.

"I saw this light blue Lincoln at the stop light just down from the church, and there was a guy hanging out waving and honking the horn," the bride explained.

"I didn't think anything of it.....by the time we got to the front of the church, the car pulled up, and this guy hops out and runs up to me!

He says, 'Hey, I'm Tom Hanks, and I just wanted to say good luck!'"
