John Legend, Chrissy Teigen, and their children visited Springfield this weekend for Legend’s dad, Ron Stephens’, birthday.

The family not only celebrated Stephen’s 70th birthday, bu also the debut of the latest Popz Topz designs.

Popz Topz, a hat company, was started in 2012 by Stephens with the hats being sold mainly online at popztopz.com.

The Upper Valley Mall in Springfield has served as a showcase for the business for the past two years.

Saturday’s event featured upcoming products including an all leather hat, a wool design, as well as more colors and a line geared towards women.

Stephens hopes to have a retail location for his brand. He said the shop would either be in Springfield, his hometown or in Columbus, where he currently lives.

While in Springfield, Chrissy Teigen posted a video of their son, Miles, dancing with the caption, “oh you at the Emmys?? well Miles and I are jamming out at grandpa Legends’s 70th birthday in Springfield, Ohio!” via Twitter.

Another video, showed a cinnamon bun pie from the Milk Bar Store cookbook. “It’s stuffed with “liquid cheesecake” filling and topped with a brown sugar and oatmeal crumble,” Teigen said.

Photos of the family on Instagram included Legend with “Granny Stephens,” Miles with his grandmothers, and their daughter, Luna, taking a nap at granny’s house, according to the captions. Below are the photos:
