New bride, new baby! Kailyn Lowry welcomed son Lincoln Marshall Marroquin with her husband Javi Marroquin, the "Teen Mom 2" star exclusively tells Us Weekly.
The bouncing baby boy was born on Nov. 16 at 4:28 p.m. and weights 8 pounds, 6 ounces.
"I am exhausted, but we are so excited and surprised by our new baby boy," Lowry told Us.
Multiple sources confirmed to Us Weekly in March that the two were expecting their first child together. "They are overjoyed to give Isaac a sibling," an insider revealed to Us at the time. "Kail is thrilled!" (Isaac is Lowry's 3-year-old son from her previous relationship with ex Jo Rivera.)
Weeks before giving birth, the reality star joked about waiting for the little bundle of joy to arrive. "Taking the dogs for walk in hopes of the baby deciding to make his or her appearance into the world," she tweeted Oct. 30.
Lowry, 21, and the U.S. airman dated for a year before tying the knot back in September 2012. One year later, the couple celebrated their wedding at Adventure Aquarium in Camden, New Jersey, on Sept. 21.
