Alyson Hannigan's baby bump is growing bigger by the minute, leading some to believe she might be carrying twins.

"The last couple of times I've been at stores, people have been like, 'Oh you're ready to pop, right?'" she says on The Rachael Ray Show (airing Friday). "I'm like, 'Actually I have a couple more months.' Somebody said, 'You're sure there's not two?' I keep asking my doctor the same thing."

Hannigan, who is due this June, says she was eager to learn her baby's gender. "I want all of the information," she admits. "My husband [Alexis Denisof] is like, 'Let's not tell the world yet.'"

The actress, 38, also spoke fondly of her daughter Satyana, who recently turned 3. "I see parts of me [in her]," Hannigan says. "I definitely see so many similarities. The books that I loved, she loves."

"She's so cute," Hannigan gushed. "The outfits she chooses are hilarious. She'll just put on a dress and then say, 'I want a purple tutu,' and then she'll put that over the dress."

Satyana is also a "great cook," Hannigan raves. "She and I bake together, and then her dad's taught her how to make scrambled eggs. We have an edible garden in our yard and she picks from it; it's fantastic."

Hannigan's new film, American Reunion, is in theaters Friday.
