For years, Giuliana and Bill Rancic have made their struggle to conceive publicly known, which is why their Monday announcement that they are expecting their first child via a gestational carrier comes as a huge and happy surprise to their supportive fans.

The Giuliana and Bill stars, who have been through failed IVF treatments and a miscarriage, plan to open up more about their decision in a 30-minute Style Network special, Giuliana & Bill: Baby Dreams, airing Tuesday at 9 p.m. EST. But they're not the first Hollywood parents to have a child through a surrogate.

On December 28, 2010, Nicole Kidman and Keith Urban had daughter Faith Margaret via surrogate in Nashville. "No words can adequately convey the incredible gratitude that we feel for everyone who was so supportive," the duo, who also have daughter Sunday, 3, told Us in a statement.

Seven years after having son James Wilkie, Sarah Jessica Parker and Matthew Broderick welcomed twins Marion and Tabitha in June 2009. "Meeting your children rather than giving birth to them, it's as if it's -- suspended animation," Parker told Vogue. "It's as if everything disappears for a moment, and the world goes silent."

Long before Kelsey Grammer and Camille Grammer's bitter divorce battle, the former Frasier star and his wife of 13 years had two kids via surrogate: daughter Mason and son Jude.

"This was our last stop," Bill, 40, explained on Today about his and Giuliana's efforts to conceive. "This was it. We had those two embryos that we had banked prior to learning about the breast cancer, and with the medicine she was on, this was our last effort. The prayers were answered."
