Elisabeth Hasselbeck is expecting her third child. In fact, she says she was knocked up without even realizing it!

"I'm pregnant again!” she announced Thursday morning on The View. "I'm due in August. I'll try to pop this one out before we leave [on summer hiatus], Barbara."

The 31-year-old and her husband, Tim, 30, are already the proud parents of 3-year-old daughter Grace, and son Taylor Thomas, who just celebrated his first birthday Nov. 9.

"We were thoroughly happy with the surprise of it," she said. "I didn't even know for two months."

Hasselbeck said her husband, Tim Hasselbeck, and herself were happy with their surprise. The Hasselbeck couple did not know about her pregnancy for two months.

Elisabeth Hasselback said she realized she became pregnant after the Inauguration on Jan 20. Hasselbeck said she felt tired, nauseous and worn out.

The ardent Republican added that she thought she was tired from the hoopla of the election, but "No – I was knocked up and didn’t realize it!"

Elisabeth Hasselbeck is married to Tim Hasselbeck, a former football player. The couple’s two earlier children are Grace Hasselbeck, 3, and Taylor Hasselbeck, 1. Elisabeth Hasselbeck is expected to deliver her new baby in August 2009.
