The former reality star announced her pregnancy back in March by posting a sweet photo of herself cradling her baby bump alongside the couple's pup, Nacho Cilantro.

"So everyone has been waiting and waiting and waiting and frankly I'm tired of everyone telling me to lock it up… I mean if you know Jill she will loose the ring," Justin shared with fans. "So I came up with the best invention ever for the love of my life. A little baby miracle in her tummy."

The 36-year-old star and her longtime boyfriend shared that they began trying for a child late last year, and were eager to welcome their little one.

"Words can't express how lucky and blessed we feel to introduce a new life into ours and that our wish has finally come true," Justin added.

Congratulations to the couple!
