Elisabeth Hasselbeck has announced she is pregnant and expecting her third child this summer.

"I'm pregnant again!," the former Survivor: The Australian Outback castaway-turned-The View co-host said on the ABC talk show's live broadcast on Thursday morning.

Hasselbeck acknowledged that the pregnancy had been a surprise, but added that she and her husband Tim, a former Boston College quarterback and her college sweetheart whom she married in July 2002, were "thoroughly happy" about it. 

"I didn't even know for two months," Hasselbeck said. "I was walking around [and] I kept saying 'It's Election Night, it's Election Night' because I was tired, I was nauseous, I thought I was worn out from the whole procedure.  No, I was knocked up and didn't realize it."

Hasselbeck has used The View to reveal all three of her pregnancies.

In September 2004, Hasselbeck used ABC talk show to announce that she and Tim were expecting their first child, Grace, who was born six months later on April 6, 2005.  In March 2007, Hasselbeck announced on The View once again that she would be expecting her second child. On November 7, 2007 she gave birth to Taylor Thomas Hasselbeck.

Hasselbeck said that she was due in August when The View's hosts will be on vacation, but told host Barbara Walters that she would do her best to give birth while the show was still airing.

"I'll try and pop this one out before we leave Barbara," she joked.
