Sarah Chalke and her fiancé, Jamie Afifi, welcomed their first daughter two and a half months ago, Us Weekly reports
According to Us, the couple named the child -- their second -- Frankie, as a tribute to the 39-year-old Scrubs star's grandfather.
Chalke and Afifi are already parents to a 6-year-old son, Charlie.
"I'm madly in love with my kid," Chalke told Us about her newborn. "It's been really fun."
Chalke confirmed her pregnancy news in April after debuting her baby bump at the Vanity Fair and Stuart Weitzman Luncheon to celebrate Elizabeth Banks in Los Angeles in February.
