Texas country star Granger Smith helped his wife Amber welcome their second child into the world Tuesday morning (Jan. 7). Lincoln Monarch Smith joins 2-year-old London as the singer’s No. 1 fans. Everyone is said to be doing very well.

Lincoln arrived without incident, weighing just under eight pounds and measuring nineteen-and-a-half inches. Granger and Amber knew Jan. 7 was their big day ahead of time. Lincoln's due date was not until Jan. 11, but the birth was scheduled early.

"With a full heart, I announce the birth of our son Lincoln. Mom & big sister are good," Smith writes, sharing the news via social media.

Daughter London was born in October 2011, about 20 months after the couple married. Amber is the star of many of the singer's videos -- the couple actually met on the set of 'Don't Listen to the Radio. She also appeared with Smith in Josh Abbott Band's 2011 ‘Oh, Tonight’ video, which also features Kacey Musgraves.
