"It's nice not to have to keep a secret anymore. We're beyond thrilled," Rosenbaum added.

Hebert and Rosenbaum fell in love on the reality show three years ago and married in a televised ceremony December 2012. After trying to conceive for two months, they decided to take a test while visiting Santa Barbara, Calif., for Bachelor stars Sean Lowe and Catherine Guidici's wedding in January. "That's when we officially found out — of course it would be at a Bachelor wedding!" Rosenbaum said.
