Sally, who wrote for the series Rodney, popped the question the day after Christmas in an elaborate proposal.
According to Shepherd's rep, after returning from a trip to San Diego, "Sherri was surprised to find their accommodations had been decorated with lights by one of Sal's best friends, her dog was wearing a Santa beard and hat, and, in the middle of a dish of Sherri's favorite but forbidden M&M's (she is diabetic), was a tiny little box."
The couple, who have been dating for more than a year, are planning to wed in August in Chicago. Shepherd was previously married to Jeff Tarpley, with whom she has a son.
Shepherd, 43, will discuss the engagement when The View returns on Jan. 10.
