Watch Zac and Vanessa's message.
"We've heard so many wonderful things about you guys," Vanessa says.
"So we decided to give Nate a hand in decorating your rooms," Zac says. "Me and Vanessa pulled a few strings, and we got you some of our favorite props from the movie."
Now the girls can't wait to get inside their bedrooms! Lily used to share a room with Izzy, but now she has her very own space, with beautiful furnishings by Pottery Barn Kids. "This is all for you," Nate says. "This is your space, honey."
As for the surprise, Vanessa sent Lily a dress she actually wore in the movie High School Musical 2!
