On December 8, Brice posted an adorable photo of himself holding their little bundle of joy while the baby grasps Lee's finger. Awww!
"A week ago, I didn’t think I could be any happier," the proud papa captions the pic. "I was wrong. Our brand new baby boy, Ryker Mobley Brice, was born healthy. My heart is full."
"Sara is the strongest and most amazing woman I know," Lee adds about his wife. "She did so good, and he is perfect."
Lee and Sara got hitched in April 2013 after dating on-and-off for 12 years. Their first son is named Takoda, and they announced their latest pregnancy in September 2013.
This follows Lee getting a Grammy nomination on December 6 for his hit tune, "I Drive Your Truck." That song was named Song of the Year at the Country Music Association Awards. His latest album, Hard 2 Love, debuted at number five on the Billboard album chart in April 2012.
