Can Kelsea Ballerini figure out what song Roman's four year old son Tristan is singing? Stylz and Roman put her to the test in today's "Translating Tristan."  Here's a hint: It's one of her own songs!

During Saturday's Keith Urban cocert, Keith saw a pregnant woman holding a sign that said "Baby's First Time On Stage (and Auntie Too?)." 

He decided to bring them on stage and then this happened....

Not only did they get a selfie on stage with Keith, but also his wife, actress Nicole Kidman, as well!

Stylz and Roman talked to the Auntie, Kristina, about the once in a lifetime experience that she and her pregnant sister, Amy had!
