Kristin Cavallari is letting the sun illuminate her boys.

The Hills alum shared special photos of her and ex Jay Cutler‘s sons Camden, 13, and Jaxon, 12, as she enlisted them to model jewelry pieces from her lifestyle brand Uncommon James.

“We launched men’s jewelry at @uncommonjames,” Cavallari—who also shares 10-year-old daughter Saylor with the former NFL quarterback—wrote on Instagram July 16, sharing photos of her sons in chain necklaces, “so obviously I had to find the 2 cutest models available.”

One image showed Camden modeling the jewelry in a black T-shirt and matching bottoms, while his younger brother was pictured in a gray hoodie with dark shorts. The tweens also put their basketball skills on display, with Jaxon dribbling a ball in another snapshot.

And while Kristin has refrained from posting pictures of her kids’ faces in the past, the 39-year-old is more open to sharing glimpses of Camden, Jaxon and Saylor these days. As she previously explained, her children are getting “a little bit older now” and have expressed an interest in social media.
