As rumors about a potential adoption continue to swirl, Katherine Heigl says that she has "great aspirations of having a big family" with husband Josh Kelley. The 29-year-old Grey’s Anatomy actress is realistic about the work load that that would entail, however. Speaking at the Peter Alexander Flagship Boutique Grand Opening and Benefit last night, Katherine admits that she is "a little afraid of saying that out loud" because she "might have one or two [children] and call it a day," adding "I get tired easily!"

Katherine and Josh were married in December 2007.
