Cape Town – It’s the final countdown to the day Jordin Sparks and husband Dana Isaiah welcome their baby boy.

But before his arrival, the No Air hitmaker shared the sound of his strong heartbeat during an ultrasound.

“I've heard many beautiful noises & sounds in my short time on this earth but this...this is the ultimate,” Jordin wrote alongside a video of herself listening to the baby’s heartbeat.

“We're ready for you when you are!” She added.

Jordin, 28, and Dana, 25, secretly tied the knot while on holiday in Hawaii in July 2017. They revealed their nuptials as well as their baby news in a People magazine exclusive in November.

The couple first met over the Easter Weekend in April after chatting over the phone for a month.
