Jessica and Cody announced their daughter's birth during the Wednesday episode of her "Now What?!" podcast, according to Us Weekly.

Jessica, 28, apparently had to undergo an emergency C-section after experiencing high blood pressure.

"After all the prep and everything, 15 minutes later on St. Patrick's Day, our little bundle of joy arrived," Cody reportedly gushed on the podcast.

Maverick reportedly weighed six pounds and seven ounces at the time of her birth, and she measured 18.5 inches long.

Maverick arrived a little early considering Jessica's due date was April 11.

Jessica and Cody, who met and fell in love on Big Brother's 19th season in 2017 and then got engaged shortly after winning the $1 million on The Amazing Race's 30th season, announced they were expecting Baby No. 1 in September 2018.

"WE'RE PREGNANT! And I'm over the moon!" Jessica captioned their Instagram reveal at the time. "I'm so excited to bring our first child into this life we have created together!"

Jessica continued in her post at the time, "I've been pretty quiet on Instagram lately. I've been avoiding posting stories and photos as much as I normally do because we've been taking this time to really enjoy all the great blessings we have in our life."

Jessica admitted that since her February 13, 2018 engagement was leaked before she and Cody could share the news with family and friends, it was wonderful for the pair to enjoy some privacy at the beginning of Jessica's pregnancy.

"It's been so great to be able to share our new addition with our loved ones before making this announcement!" said Jessica.

While Maverick is Jessica's first child, Cody, 33, is dad to a daughter named Paisley from a previous relationship.

Jessica and Cody tied the knot in Malibu, CA, at The Chateau Le Dome at Saddlerock Ranch in October 2018 and revealed just one day later they had a baby girl on the way.

Jessica did not debut her baby bump until December 2018 when she was 22 weeks along in her pregnancy.
