Country singer Jessie James and her husband, New York Jets wide receiver Eric Decker, will be celebrating their daughter Vivianne Rose's first birthday this month -- but that's not all they've got to celebrate. The couple has announced that they're expecting a second child!

"Vivianne is so excited because she is going to be a big sister!" James posted on Instagram on March 2, along with a photo of her family wearing swimsuits and smiling in the sunshine. "We are over the moon about having another baby!!!"

The couple got married in July of 2013 and announced her first pregnancy that September. Baby Vivianne was born on March 18, 2014, weighing 8 lbs., 2 oz. and measuring 20 inches.

"[Eric] changes all the diapers willingly," James tells People. "[He] gets up with her most of the nights because I’m a hard sleeper -- it’s not that I don’t want to wake up, but she cries and I don’t hear it sometimes."

The 26-year-old James released an EP, Comin' Home, in April of last year. She's currently serving as a co-host of Season 4 of CMT's reality show Redneck Island, along with wrestler Steve Austin.

Congratulations to the growing family!
