Ernie Halvorsen and Cindy Chiang, who won The Amazing Race in 2011, have welcomed their second child.

Chiang, who took Halvorsen's last name when they wed, gave birth to the couple's second son whom they named Ernest Zhang Halvorsen, People reported.

Ernest arrived at 7:06PM in Chicago on Tuesday weighing eight pounds. He also measured 20 inches long.

"Our second-born carries the name Ernest into a fifth generation of Halvorsen men," Chiang told People. "We're calling him 'Finn,' which is an old nickname for the five-dollar bill."

The newborn joins the pair's 21-month-old son Maverick Zhang, who is apparently thrilled to be a big brother.

"Maverick is the sweetest big brother," Chiang said. "He loves to hug and kiss Finn! We're exploding with happiness as a family of four."

With two little boys in the family now, the former Season 19 Racers are thrilled.

"Creating our family together is our greatest and most fulfilling adventure," Chiang continued. "We're so lucky to be parents to these two amazing little boys who fill our hearts with love and laughter."

When the couple competed on The Amazing Race, they were engaged. They defeated runner-up "Dating Couple" Jeremy Cline and Sandy Draghi.
