It's a busy week for Jo Dee Messina. Fresh off her Sunday night appearance on 'The Real Housewives of Atlanta,' the country singer has given birth to her second son at a Nashville hospital.

According to a statement issued by her publicist, Messina and husband Chris Deffenbaugh welcomed Jonah Christopher into their family. Little Jonah arrived at 2:43 PM CT this afternoon, Jan. 11, weighing in at 6 pounds, 13 ounces. Jonah joins older brother, Noah, 3.

Messina checked in from the hospital after delivering Jonah, saying, “Noah couldn’t wait to hold his little brother. He’s so good with him. God has blessed us so much.”

Congratulations to Messina and her family on their precious blue bundle of joy.

It's worth a mention that Messina recently tweeted good tidings and sleep advice to pop star Beyonce, who welcomed her first daughter on Saturday, Jan. 7.
