TELEVISION - July 9, 1991

Mommy No. 3: Mary Page Keller, who starred on Fox’s now-defunct “Duet,” will become the third actress hired to portray single mother Maggie Campbell on ABC’s “Baby Talk,” the network announced Monday. Keller, who most recently had the recurring role of Gina Giordano, sister of Libby Thacher (Patti LuPone), on ABC’s “Life Goes On,” succeeds Julia Duffy, who was released from her contract to become a regular on CBS’ “Designing Women.” Connie Sellecca was the first Maggie but was dropped before production began last year.
