HOLLYWOOD, Calif. — Sarah Chalke is pregnant!

The 32-year-old "Scrubs" star and her fiancé, entertainment lawyer Jamie Afifi, are expecting their first baby, the star's rep confirmed Friday.

The couple's baby will arrive this winter.

Chalke and Afifi got engaged in December 2006 while vacationing in Hawaii.

"The best is just knowing that 100 percent somebody always has your back and you always have theirs," she told People earlier this year about engagement life. "You have a partner, you have a buddy."

Sarah Chalke first gained notoriety in 1993 when she took over the role of Becky (Conner) Healy on "Roseanne" from Lecy Goranson.
