"Our lives have changed so much in the last two years and today we've been blessed with the best change ever, our beautiful baby girl," Rycroft tells the magazine.
Ava Grace Strickland, who weighed 6 lbs., 13 oz., is the first child for the couple. The pair tied the knot in Mexico in December 2009.
Rycroft is perhaps the most famous jilted contestant on reality TV. The Bachelor's Jason Mesnick gave her his final rose in Season 13, but by the time of the reunion show, his feelings had changed. He dumped her on the special, transferring his affections to runner-up Molly Malaney. Mesnick and Malaney married in 2010.
