The cute brunette shared the news with InTouch Weekly.
"I'm a little nervous, but we're very excited," Hebert said. "I've wanted a child for a while."
Rosenbaum added, "It's nice not to have to keep a secret anymore. We're beyond thrilled!"
The couple went through a few tests that were unclear at first, but took another at the Santa Barbara, Calif. nuptials in January. "There was legitimately a line," Rosenbaum said. "That's when we officially found out -- of course it would be at a Bachelor wedding!"
