‘Teen Mom 2’ star Kailyn Lowry has welcomed her second child into the world – a son with her husband Javi Marroquin.

Us Weekly reports that Lincoln Marshall Marroquin was born on November 16 at 4.28pm weighing 8 pounds, 6 ounces.

“I’m exhausted, but we are so excited and surprised by our new baby boy,” the MTV star told the website.

Kailyn has also tweeted about her baby joy, sharing yesterday: “So in love with this new little boy.”

Lincoln is the second child for Lowry, who has a three-year-old son named Isaac from her previous relationship with Jo Rivera. The 21-year-old and her now-husband Javi tied the knot in September 2012.

Kailyn’s pregnancy with Isaac was documented in MTV’s own reality series ‘16 and Pregnant,’ and ‘Teen Mom 2’ now chronicles her journey raising her son.

Congratulations Kailyn and Javi!
