Bachelor in Paradise alum Jade Roper is a first-time mom.

The 30-year-old reality star announced in an Instagram post Thursday that she welcomed a baby girl with husband and Season 2 co-star Tanner Tolbert.

"We did it! Our little sweetheart is here!" Roper captioned a photo of herself with Tolbert and their daughter. "She arrived on her own terms, quickly and 4 weeks early, but she is perfect in every way, healthy and doing well."

"Precious little girl, there are no words to describe the feeling of holding you in our arms for the first time and looking into your beautiful eyes. We love you so much. #bestdayever #ilovemyfamily," she added.

Tolbert also celebrated the news by sharing a picture of his family on his own account.

"Love my girls... @babyjanner arrived this morning at 10:03 AM... she decided to surprise us and come a little early... but mom and her are doing great... Best day of my life," he wrote.

Roper and Tolbert competed on The Bachelor Season 19 and The Bachelorette Season 11, respectively, before meeting on Bachelor in Paradise and getting engaged on the Season 2 finale. The couple married in January 2016, and announced Roper's pregnancy in March.

"We're crazy grateful to finally announce a little secret we've been keeping," Roper tweeted at the time. "We're absolutely head over heels in love already!"
