“Kickin' ass and takin' names. Back stage w the Houghs. And #lexi + #harley. @juleshough @derekhough @moveliveontour,” Nina captioned a photo montage of herself with the Houghs and puppies Lexi and Harley. One big happy family! Nina apparently surprised her good friends by showing up at their Chicago performance. “Surprise!!!!!!!! @juleshough @derekhough We're in Chicago! So excited to see the show!” Nina captioned this photo of herself and a friend holding up V.I.P. tickets to the event.
