Jessie James Decker Gives Birth, Welcomes Baby Number Two With Hubby Eric Decker (PHOTO, TWEET)

Jessie James Decker gave birth to a son! The country star welcomed her second child with her husband, New York Jets player Eric Decker on Friday afternoon, Us Weekly reported. Decker confirmed the arrival of their second child via Twitter.

"Thanks for all well wishes! Mama and baby boy are doing great!! Vivi is the sweetest big sister!" the proud papa tweeted to his 308,000 followers, just one day after James Decker posted a sweet snap of the couple in the delivery room on Instagram, captioned simply with a heart emoji.

Decker, 28, and James Decker, 27, tied the knot in June 2013 and have a daughter together, 17-month-old Vivianne Rose, according to Us Weekly.

James Decker has documented her second pregnancy through her Instagram ever since she announced her second pregnancy in March, People reported. The couple confirmed they were expecting a son and spent no time decorating a sports-themed nursery for their new baby boy.

"We already knew the names before we even knew the sex of the baby," James Decker told People. The couple had yet to announce their new bundle of joy's name.

For her second pregnancy, James Decker gushed that things were completely different this time around compared to when she was pregnant with little Vivianne.

"It's completely different!" James Decker told Us Weekly. "Vivianne kicked my butt - I was sick every day [but] this little guy is very gentle, he doesn't make me sick. He definitely doesn't wear me out as much as she did."
