Although Hanson has known Nikki for a few years, Kat recently reached out to the brothers via social media to tell them she’s a huge fan! When the idea for the “Get The Girl Back” music video came up, the band asked the actresses to be in it. “It was a very fun thing because they [Nikki and Kat] are genuine fans of our band,” Isaac Hanson tells AOL Music. “It also didn’t hurt that they’re actually friends.”
