The twins opted for bold blue and pink floral suits, respectively, at the fashion forward event, while Hammer, 30, opted for an all-black, turtleneck look.
"It was weird and it was tough initially, especially the first couple days trying to figure out how we're going to do this, creating a system and all that," Hammer told ET's Kevin Frazier in 2010, regarding the challenge that came with depicting two characters on screen. "But then, like anything else on a great set with a great director, we found our rhythm and...were able to truck through it, and it became just an amazing process."
Hammer also revealed how hilariously funny and surreal it was meeting the twins after production, when he'd spent the better part of a year learning everything about them!
"[It was] surreal because I felt like the smaller triplet. It was so strange ... It was after production when we'd met 'em, so I'd spent the last eight months trying to think like these guys," he explained at the time. "So to finally see them, I was like, 'Dude, Cam, remember when you were 15 and you fell in the water?' and Ty, 'Your mom was like, "Oh, I'm so mad at you guys!"' and they're like, 'We just met you. You are freaking us out, dude. Pump the brakes!'"
