Kailyn Lowry wishes the best for Javi Marroquin and his growing family. The 26-year-old responded Wednesday after Marroquin, her ex-husband, announced he's expecting with girlfriend Lauren Comeau. "I wish them all the best," the "Teen Mom 2" star told E! News. Marroquin, who is parent to 4-year-old son Lincoln with Lowry, confirmed Comeau's pregnancy in an Instagram post Wednesday. "A baby is a blessing and I am ecstatic for the future. Lincoln is happy, I'm happy, and Lauren is happy," Marroquin wrote. "For those sending love, thank you! We appreciate it." "@lauren3elizabeth thank you for blessing me with another child. We are gonna be amazing parents together," he added. Lowry, who split from Marroquin in 2016 after three years of marriage, is also parent to 8-year-old son Isaac with Jo Rivera and 9-month-old son Lux with Chris Lopez. She said she's single in a tweet Monday following her girlfriend's debut on "Teen Mom 2."
