"Our new mom, Elisabeth, is back!" co-host Meredith Vieira (search) exclaimed Wednesday.
A glowing Hasselbeck emerged on the set of the show, having lost most of the weight from her pregnancy.
"It doesn't look like you've had a baby, it looks like you've had a massive breast implant," Vieira said.
The 27-year-old Hasselbeck, who is married to New York Giants quarterback Tim Hasselbeck, gave birth to the couple's first child, Grace Elisabeth, on April 6.
"Grace is amazing," she said. "She likes to eat a lot and sleep a lot — just like her father."
Her baby has been a topic of conversation for the daytime chat fest. In February, the show hosted a baby shower for Hasselbeck that included an audience full of mothers-to-be. The same group was invited back Wednesday to add to the "new mom" theme.
Hasselbeck, who was a contestant on "Survivor: The Australian Outback," led several audience members on "new mom makeovers."
