Elisabeth Hasselbeck is pregnant — again! It was just 14 months ago that The View co-host gave birth to her son, Taylor, but she announced this morning that she and her husband, NFL star Tim Hasselbeck, are expecting their third child in August. “I didn't even know for two months,” she said while sitting at the Hot Topics table. “I was knocked up and didn’t even realize it!” Aside from their young son, the couple has a 3-year-old daughter, Grace. And although Elisabeth may have been shocked by the news, she’s definitely excited. “She’s so happy,” an ABC network insider tells In Touch. “Elisabeth has made it no secret that she wants to have a big family, and she and her husband are elated about their new addition.” And her boss, Barbara Walters, will be happy as well. “Elisabeth is not expected to miss much time away from the show, as her due date is right around the summer hiatus,” adds the insider.
