Congratulations to 16 and Pregnant's Kristina Head! This gal gave birth to her second child (a baby boy!) on January 8th, and she couldn't be more thrilled. Give a warm welcome to the newest member of MTV's growing family, Tommie Joseph, the sweetest bundle of joy this side of Mississippi. "Love him so much," Kristina posted on Instagram along with the cutest picture of Tommie ever.

Kristina was featured on 16 and Pregnant after getting knocked up by her baby daddy, John Todd Hight Jr., who tragically drowned while swimming with Kristina off the coast of Galveston, Texas with Kristina and while she was still pregnant. Their adorable baby, Lukas Todd, was born prematurely on Sept. 26, 2011, and we have no doubt that he's going to be a great big brother!

Nowadays, Kristina is happily married to her hubby, TJ Head, who popped the question in December 2011. They made it official on March 8, and haven't looked back since! Congrats on the new addition to your family, ya'll!
