"Welcome to the world Layton Sarti Schroeder 8lbs 7oz -- 20.5 inches. Lawson is gonna be the best Big Brother! #family," Jeff captioned photos of the parents and their adorable newborn on Instagram. "@bbjordanlloyd did such a great job! Thank you to all the amazing Doctors & nurses."
Lawson is the couple's first son, and he's now 22 months old.
And Jordan shared the same pictures on Friday, writing on her own Instagram account, "I had a great delivery last night!! Everything went so smoothly & baby Layton came into this world while Bob Marley 'could you be loved' was playing in the background."
"Couldn't have asked for a more chill delivery," she added.
"Thank you to my doctor & nurses here at the hospital! They are all rockstars. Layton Sarti Schroeder 8 pounds 7oz 20 1/2 inches."
When Jordan was in labor, she shared a video on Instagram from her hospital room.
"We're having a baby but we don't know what we're having yet!" Jeff revealed at the time. "Baby No. 2 is on the way!"
Jeff and Jordan met on Big Brother's eleventh season back in 2009.
Jordan was crowned the winner of BB11, but Jeff at least walked away with the honor and title of "America's Favorite Houseguest."
The couple -- who competed on The Amazing Race's 16th season -- later returned to compete on Season 13 of Big Brother in 2011 and then got engaged during a 2014 episode of the show's sixteenth edition.
Jeff and Jordan were planning to marry in September 2016; however, the situation changed once Jordan found out she was pregnant in February of that year.
The pair therefore wed in a courthouse on March 15, 2016 in front of their loved ones. The former reality TV stars -- who also appeared on Marriage Boot Camp -- then welcomed Lawson in October of that year.
