Tom Hanks is a certified wedding crasher.

The "Forrest Gump" star, 65, shared during Tuesday’s episode of "Late Night With Seth Meyers" that his ego goes "unchecked" when he crashes people’s wedding photos.

"It’s my ego, unchecked," Hanks said. "I just can’t help but think, ‘What would these people like more than anything else to remember this magic day of days? Oh, I know: me!’"

Hanks was a guest on the talk show to promote his latest biopic, "Elvis," which stars Austin Butler as the late music icon.

After Hanks admitted his love for wedding crashing, Meyers aired a series of photo bombs. Some of the images dated to the early 2000s.

Hanks took his wedding photobombing international while filming "Angels & Demons" in Rome. Hanks crashed a wedding by mistake when the Pantheon was booked for a wedding service the same day the crew was scheduled to film.

"This limousine pulled up, and it was the bride and the groom trying to ‘get me to the church on time,’" Hanks began. 

"And they couldn’t do it because we had all this stuff going on. It was like, ‘Uh, how do we fix this?’ So, like a stalker, you know, ‘Hey miss, miss, miss!’ I knocked on the window, I said, ‘Hey listen, we have a thing, but would you do me the honor of escorting you to your bridal altar?’ So we did it!"

In March, Hanks photobombed a bridal party’s photo shoot outside the Fairmont Hotel in Pittsburgh. Grace Gwaltney, the bride, revealed she was "shocked" to see Hanks. 

"He was like, 'Hey! I'm Tom Hanks. I would love to get a photo with you,' and I immediately froze and was just looking around," Gwaltney told KCRA. "I didn't know what to do."
