This will be the first child for Bell, 32, and Shepard, 37, who began dating in 2007 and have been engaged for nearly three years. The timing was right for the Hit and Run costars to start a family, multiple sources tell Us. "She and Dax are so cute and in love. They are the real deal," an insider says. "They laugh all the time. He is so respectful to her. . .chivalry isn't dead for him. He opens doors and takes care of her."

"We wouldn't want to invite all of our friends who don't have that right to celebrate us, who have that right," Shepard said on The View in July. "We just don't feel right about that."
