"Today we welcomed Charlotte Jeanne #Csincsak into the world ! Our lives will forever be changed ! We are so excited !!" Csincsak, the 31-year-old former fourth-season The Bachelorette winner, captioned a photo of his daughter's footprints on Instagram Monday.
Charlotte Jeanne, who is just about 20 inches long, was born in Colorado at 8:03AM weighing seven pounds and six ounces, Peoplereported.
"Ann is just resting and Charlotte just had her bath. We're good!" Csincsak told People.
Csincsak and Lueders, who's a former thirteenth-season The Bachelor bachelorette, are already parents to a three-year-old old son named Noah Theodore.
"Noah is on his way to meet his baby sister right now," the proud dad added.
The couple announced they were expecting their second child in September 2013 although they found out about the pregnancy in June of last year.
Csincsak broke up with Pappas in November 2008 and then dated twelfth-season The Bachelor bachelorette Holly Durst before he and Lueders began their relationship.
Csincsak and Lueders then got engaged, announced they were pregnant with their first child, and got married all within August 2010. Lueders took the name Csincsak when they exchanged vows. Noah later arrived in February 2011.
