Jessie James Decker and husband Eric Decker have welcomed their second child into the world.

"Thanks for all well wishes!" Eric wrote on Twitter on Friday. "Mama and baby boy are doing great!! Vivi is the sweetest big sister!"

Jessie shared a personal photo of herself in a hospital bed as she was in labor on Thursday. She had a serious look on her face as she nuzzled herself into Eric's head. He had his arm around her and boasted a big smile.

The couple already has a 17-month-old daughter Vivianne Rose, so Eric is looking forward to having a son as well.

"I'm just looking forward to being out in the backyard and kicking around a football and a baseball bat, a golf club, just sporty stuff," the NFL player recently told E! News. "When I was growing up, I always wanted that boy that I could play around with, give him the opportunities to do what I did so I'm excited."

Jessie's second pregnancy was apparently "easy breezy" compared to her first.

"Running after Vivianne all the time, I was able to stay in shape and only gained 24 pounds. They say pregnancies can differ depending on whether you're carrying a girl or boy, so for me I think having a little boy is definitely easier on my body -- or I'm just better prepared!" the "Lights Down Low" singer admitted in her pregnancy blog.

While the parents are ecstatic to have two children now, they're open to the idea of expanding their family even more. Eric, more so, would love a large brood.

"Two or three [kids]. It used to be four but who knows with this one," Jessie said before pointing at her husband. "He might be trying for a fifth and he'll be sneaking in again."

For a celebrity, it's refreshing Jessie isn't obsessed about getting her post-baby body into shape.

"The first months are a time to focus on your newborn, not on losing weight," she explained to E! News. "I think the old saying that it takes ten months to put the baby weight on and another ten months to lose it is probably very accurate."

Decker and James got engaged in April 2012 and got married in June 2013. They both star on Eric & Jessie: Game On, which was previously titled Love and Other Contact Sports. The series premiered in September 2013.
